Do not take legacy property into account if there's non-legacy value.

Moves the things around to be able to override the config with the URL
params specified in the hash part of the location URI to which the app
is navigating to.

* add a prosody module to insert identity information (when available) into
presence

prosody will check for jitsi_meet_context_user and
jitsi_meet_context_group in the session and, if they are present, insert
them into presence (we do this in prosody so they cannot be spoofed).

* remove unused 'presence' variable

* refactor to modify presence message in place

* make object member access consistent

* make the group information optional

Hardcoding an offset from the bottom of 32px causes issues in
horizontal filmstrip when there is no invite button, because
then the local video just displays 32px from the bottom as there
is no button to take up space above it. Instead leverage flex
alignments to align the bottom of the video to the bototm of
the filmstrip.

fix(analytics): Init analytics for the web welcome page.

* doc: Add webpack-dev-server steps

fix(info): update copy text to find correct var

feat(UnsupportedMobileBrowser): do not include protocol in the intent

Do not include the protocol part in the intent URL.

Adds base/sounds feature which allows other features to register a sound
source under specified id. A new SoundsCollection component will then
render corresponding HTMLAudioElement for each such sound. Once "setRef"
callback is called by the HTMLAudioElement, this element will be added
to the Redux store. When that happens sound can be played through the
new 'playSound' action which will call play() method on the stored
HTMLAudioElement instance.

The animation for toggling filmstrip visibility was lagging on
Safari. Even though the background video is set to hidden, it is
still causing issues. Setting the background to display none
instead does help but might interfere with animations. So instead
do the easy thing and re-use logic used for Firefox to not show
the background video.

Pre-existing logic made it so numbers were assumed as valid
if no validation url was specified. To be consistent with
the validation server, the faked number should include a
+ at the beginning.

* feat(invite): be able to call numbers from the invite dialog

The major changes:
- Remove DialOutDialog, its views, redux hooks, css, and images.
  Its main functionality has been moved into AddPeopleDialog.
- Modify the AppPeopleDialog styling a bit so it is wider.
- Add phone numbers to AddPeopleDialog search results. Phone
  numbers are validated in parallel with the request for people
  and then appended to the result. The validation includes
  an ajax to validate the number is recognized as dialable by
  the server. The trigger for the validation is essentially if
  the entered input is numbers only.
- AddPeopleDialog holds onto the full object representation of
  an item selected in MultiSelectAutocomplete. This is so
  selected items can be removed on successful invite, leaving
  only unsuccessful items.
- More granular error handling on invite so individual invitees
  can be removed from the selected items list.

* squash: change load state, new regex for numbers

* squash: change strings, auto prepend 1 if no country code, add reminders

In 94813bc0fd (diff-6e9552c9bd8e61c8f277c21220160234)
two local variables got removed (AUTH_KEY_FILE and AUTH_CRT_FILE), which are used by the sed command
below to configure the virtualhost for auth.

For the static page an error message displays stating no room
was specified. On mobile for unsupported browsers, the dial in
info will not show.

The new libwebrtc.jar contains an extra unused class file, when proguard is enabled result in the following warning:
