Removes ' character which should not be there.

'_isConnectionActive' is not used anymore

The default for 'show' argument of 'showRemoteConnectionMessage' is
undefined (unspecified).

Simplify 'updateParticipantConnStatusIndication' by getting rid of
'showMessage' argument.

Also moves the logic about participant connection status from SmallVideo
to RemoteVideo, because it doesn't make sense for local videos.

Add ninja icon which wil be displayed when user's connection status is
inactive.

Apply grey filter only for interrupted state.

Do not use isLastN directly, but check ParticipantConnectionStatus.

Rewrite the non-React RingOverlay into the React Component CallOverlay
in a way which makes it easier to port to React Native.

Introduce certain React Components which may be used to write
cross-platform source code such as Audio like Web's audio, Container
like Web's div, Text like Web's p, etc.

* fix(large-video): ensure switch to local video when all others leave

This handles the case where User A and B are in a call and B has
no audio or video. Then B leaves. User A would see User B left
on large video. Instead, User A should see self view on large.

* squash: always update large video if it is empty

* squash: add largeVideo check for filmstrip only mode

* include local.html file meant to define local analytics properties
include all specified local analytics properties in analytics events

* use new variable name jitsiDeploymentInfo to represent more general use as local deployment information collection

The counterpart of the external API in the Jitsi Meet Web app uses the
search URL param jwt to heuristically detect that the Web app is very
likely embedded (as an iframe) and, consequently, needs to forcefully
enable itself. It was looking at whether there was a JSON Web Token
(JWT) but that logic got broken when the JWT support was rewritten
because the check started happening before the search URL param jwt was
parsed.

It is possible for a connection update to come during a large video update,
between its promises, which would result in the update NOT triggering another
large video update because an update is in progress. This can cause a state
where a connection status overlay is displayed over a video in a state that
does not match the actual video state, like the restoring overlay displaying
on active video.

Fixes using public key to verify tokens.
Tested in production.

Fixes a TypeError: Cannot set property 'innerHTML' of undefined
                    at o (Chat.js:61)
                    at Object.updateChatConversation (Chat.js:271)
that is thrown when joining a conference with messages already set to the chat. The error used to remove a strophe handler and chat was not working at all for those seeing the error.

* fix(large-video): trigger update after timeout for 1-on-1 calls

Currently no video switch happens if a user joins audio and video
muted. For example, User A is in a call and User B joins with no
mic and camera. User A will keep seeing local video on large video.
The fix is to set a timeout, of a somewhat arbitrary 3 seconds, to
show User B on large video.

* SQUASH: wrap videoElement access in if

* SQUASH: split out remoteVideoActive logic

We've had Filmstrip & LargeVideo React Components on mobile/React Native
from the start. We didn't have them on Web (because the rewrite in React
is not complete yet). However, that led to differences in the React
Component Conference on Web and mobile. In an effort to get closer to
merging the React Component Conference on Web and mobile, introduce the
React Components Filmstrip & LargeVideo on Web even if a minimal
render-only form at this time.

fix(video-label): Show darker background on hover

* fix(vertical-filmstrip): different label animations for filmstrip states

Instead of one timing for sliding the video status label left and right,
have different timings depending on the filmstrip state. To facilitate
triggering the different animations, add more classes to the labels
that need to move that specify the filmstrip state.

- Faster transition if focusing on self-view with videos present so
  the label does not overlap videos transitioning from 0 opacity.
- Transition delay when de-focusing on self-view with videos present
  so videos have time to go away before the label moves over them.
- Maintain no movement if there are no videos, regardless of
  filmstrip toggle state.
- Different delays for when the filmstrip is being toggled visible
  and hidden if there are remote videos visible.

* SQUASH: remove remote videos count

* SQUASH: add docs to scss

Disables speaker stats in filmStrip only mode.

fix(filmstrip-only): hide video label, always show remote thumbnails

fix(video-label): modify z-index and cursor

fix(vertical-filmstrip): do not move recording label if not in the co…

- Change z-index so any tooltips that display over the label,
  particularly in vertical filmstrip mode, actually hide the label.
- Change the cursor to be a pointer so the label looks clickable.
- Remove unused audio-only-label styling.

Re-styles scrollbars
