Only one notification will be displayed at a time on mobile.

Adds 1 liner notifications to mobile. Only the title is displayed. In
case the title is missing there's a fallback to the description.

If user dismisses the not topmost notification the timeout will be
cleared and a new one will not be set, because the top notification
remained the same (see the if at line 90).

The docs of 'componentDidUpdate' say that it's not called for the
initial render. If the component is added to the DOM with 1 notification
already, then the update will not happen and timeout will never be set
which will effectively break the timeouts chain.

Using anything non-serializable for action types is discouraged:
https://redux.js.org/faq/actions#actions

In fact, this is the Flow definition for dispatching actions:

declare export type DispatchAPI<A> = (action: A) => A;
declare export type Dispatch<A: { type: $Subtype<string> }> = DispatchAPI<A>;

Note how the `type` field is defined as a subtype of string, which Symbol isn’t.

This new version comes with an updated JSC runtime, so we no longer need to
depend on the updated version ourselves.

* Removes unused ADD_PEOPLE_APP_NAME
* Moves deep-link header background and logo size as variables.
* Fixes more numbers page space in the header.
* Fixes left padding on deep-linking mobile page.

Consolidate all failure cases into a single one: CONFERENCE_TERMINATED. If the
conference ended gracefully no error indicator will be present, otherwise there
will be.

That's what the SDK passes now, if the room URL is not absolute.

There is no need for AbstractApp to require some getWindowLocation function.
It's only used in one place and we even polyfill it on mobile.

Thus replace it's usage with more specific functions.

It's now all handled in the SDK an we'll get the new URLs via props.

* Updates recording dialog.

* Update config.js doc.

* Adds comment and make a check more intuitive.

* Changes of using enum for recording types.

Seems like windows does not have emojis for flags.

* Adds new format of phoneList service and re-design dial in numbers page.

Adds flags and country names (with translations) for the numbers if using the new format.

* Fixes tests and fixes get default number.

* Updates swagger with new format.

* Moves html back yo table.

Fixes displaying on mobile and also the tel: URI generation. The tel: URI is tested on Android and iOS and seems to work (Android was not interpreting 'p', but both seems to like ',').

* Fixes a wrong return statement.

* Small fixes.

Adds a new event fired when Jitsi Meet shows the feedback prompt.

The conference disconnection process is asynchronous which means there's
no guarantee that there will be CONFERENCE_LEFT event for the old
conference, before the next conference is joined. Because of that we can
end up with two simultaneous calls on the native side which is not
always supported. End the call on CONFERENCE_WILL_LEAVE to fix this
corner case.
