Video elements may have problems scaling to cover pixel fractions,
so there could be a 1px black border line displaying in the
thumbnail. It's most visible in tile view. Flooring the sizing
calculations hides the border.

* feat(tile-view): initial implementation for tile view

- Modify the classname on the app root so layout can adjust
  depending on the desired layout mode--vertical filmstrip,
  horizontal filmstrip, and tile view.
- Create a button for toggling tile view.
- Add a StateListenerRegistry to automatically update the
  selected participant and max receiver frame height on tile
  view toggle.
- Rezise thumbnails when switching in and out of tile view.
- Move the local video when switching in and out of tile view.
- Update reactified pieces of thumbnails when switching in and
  out of tile view.
- Cap the max receiver video quality in tile view based on tile
  size.
- Use CSS to hide UI components that should not display in tile
  view.
- Signal follow me changes.

* change local video id for tests

* change approach: leverage more css

* squash: fix some formatting

* squash: prevent pinning, hide pin border in tile view

* squash: change logic for maxReceiverQuality due to sidestepping resizing logic

* squash: fix typo, columns configurable, remove unused constants

* squash: resize with js again

* squash: use yana's math for calculating tile size

The flag is always false.

The animate flag is always being passed in as false, so
essentially the animation isn't needed, unless a setTimeout 0
behavior is for some reason required...

jquery animate during animations sets an element's overflow to
hidden and then back to the overflow declared before the start
of the animation. If multiple animations are fired, then the
overflow could be set to hidden permanently. No calls
to Filmstrip#resizeThumbnails have animate set to true, so the
animate call is not even needed.

Instead of having visible and visibility and setToolboxVisible and
setFilmstripVisibility, have only visible as a name.

- Modify Etherpad and SharedVideo so their resizing takes into account
  the width of the filmstrip in vertical filmstrip mode.
- Modify Filmstrip's getFilmstripWidth to account for when the filmstrip
  is hidden.
- modify VideoContainer so in vertical filmstrip mode it centers the
  shared desktop stream in the middle of the available space not taken
  by filmstrip.
- Also allow clickthrough on the secondary toolbar itself while still
  allowing clicks on the toolbar's buttons. This allows clicks on
  shared videos to go through.

Using column-reverse prevents proper scrolling on browsers other than Safari
and Chrome. Additionally, Firefox has an issue where flex containers have
dimensions set to auto, preventing resize. So, add hacks to maintain Chrome
and Safari's behavior while allowing for some kind of scrolling on other
browsers.

* WiP(invite-ui): Initial move of invite UI to invite button

* feat(connection-indicator): implement automatic hiding on good connection (#2009)

* ref(connection-stats): use PropTypes package

* feat(connection-stats): display a summary of the connection quality

* feat(connection-indicator): show empty bars for interrupted connection

* feat(connection-indicator): change background color based on status

* feat(connection-indicator): implement automatic hiding on good connection

* fix(connection-indicator): explicitly set font size

Currently non-react code will set an icon size on ConnectionIndicator.
This doesn't work on initial call join in vertical filmstrip after
some changes to support hiding the indicator. The chosen fix is
passing in the icon size to mirror what would happe with full
filmstrip reactification.

* ref(connection-stats): rename statuses

* feat(connection-indicator): make hiding behavior configurable

The original implementation made the auto hiding of the indicator
configured in interfaceConfig.

* fix(connection-indicator): readd class expected by torture tests

* fix(connection-indicator): change connection quality display styling

Bold the connection summary in the stats popover so it stands out.
Change the summaries so there are only three--strong, nonoptimal,
poor.

* fix(connection-indicator): gray background on lost connection

* feat(icons): add new gsm bars icon

* feat(connection-indicator): use new 3-bar icon

* ref(icons): remove icon-connection and icon-connection-lost

Both have been replaced by icon-gsm-bars so they are not
being referenced anymore. Mobile looks to have connect-lost
as a separate icon in font-icons/jitsi.json.

ESLint 4.8.0 discovers a lot of error related to formatting. While I
tried to fix as many of them as possible, a portion of them actually go
against our coding style. In such a case, I've disabled the indent rule
which effectively leaves it as it was before ESLint 4.8.0.

Additionally, remove jshint because it's becoming a nuisance with its
lack of understanding of ES2015+.

- Remove non-redux paths for hiding and showing remote videos.
- Hook web filmstrip to redux to know when to hide remote videos.
  This works, even though VideoLayout is handling RemoteVideo
  appending, because react is only monitoring filmstrip's declared
  JSX which does not change except for attributes (css classes).

With AtlasKit InlineDialog, the filmstrip z-index in vertical
filmstrip mode was adjusted as it had to be set to fixed position
for the dialogs to automagically be position fixed. This left
behind a regression where the filmstrip z-index was the same as
the video quality label, but came later in the dom, so the label
was not clickable. This commit modifies the z-index of the
vertical filmstrip to account for clicking of the video quality
label.

Vertical filmstrip has a scrollbar to scroll through all remote
video thumbnails instead of scaling width and height to force all
thumbnails to display on screen. The scaling is not necessary in
vertical filmstrip mode and instead causes some UI spacing issues
with the video status label.

Also addressed a typo in "removeVideoWidth" near the area of the
changed logic.

The video status labels, which include recording and hd status,
have been moved back to the top left while in vertical filmstrip
mode. The following had to be done:
- Remove styling to move the labels to the bottom left
- For VideoStatusLabel, move filmstrip remote video count, toggle
  state, and 1:1 state into redux.
- Use middleware to emit out to the Recording label when the
  filmstrip changes.
- Create an empty Filmstrip file for web and identify the existing
  Filmstrip component as native.

- Expose an api on Filmstrip to hide the remote videos container, which does so
  by adding a class
- Modify listeners for user join, leave, share video to call the api
- Hide the container when there is 1 or fewer remote participants
- Always show the container if self view is in focus
- Show the container if the number of remote thumbnails does not match the count
  of remote participants, such as the case of sharing a video

- Add a class to the body when in vertical filmstrip mode
- Override styles as necessary to support the mode
- Add an option to make tooltips display from the left
- Move the HD Label to the bottom left
- Move the remote video menu to the bottom left, move the mute
  icons to the bottom right
- Scale the local video's height and width to fit the filmstrip

The 1:1 call UI and vertical filmstrip act on remote videos
while leaving local video alone. To facilitate acting only on
remote videos, place remote videos into their own container element.

We seemed to be using the names "film strip" and "filmstrip" (and,
consequently, their source code-conscious forms such as film-strip,
FilmStrip, etc.) In order to comply with our coding style which requires
a consistent one name for a given abstraction, choose one name and
rename the uses of the other name.

Wikipedia has a definition of a "filmstrip", I couldn't find a "film
strip". I guess our abstraction can be seen as what's described there.
When I google "film strip", I get results about "filmstrip" at the top.
That's why I chose "filmstrip".

Certain uses of "film strip" such as interfaceConfig.filmStripOnly and
in the external API I left untouched in an attempt to preserve
compatibility.

I wasn't sure whether CSS was tangled in compatibility so I made a
choice and renamed there was well.
