On RN we don't use the global APP object, so don't save the store there unless
it's defined, which is the case in the current web version. Also, check for
undefined explicitly, since a "if (!APP)" check will throw a ReferenceError.

Includes automatic recommended Xcode project file fixes.

Lib-jitsi-meet uses jQuery's .append method to manipulate Jingle. The
method in question invokes the getter and setter of Element.innerHTML.
Unfortunately, xmldom which we use in React Native to polyfill DOM does
not polyfill Element.innerHTML. So polyfill it ourselves.

Turns out React Native's timers (setTimeout / setInterval) don't run while the
app is in the background: https://github.com/facebook/react-native/issues/167

This patch replaces the global timer functions with those from the
react-native-background-timer package, which work in the background.

These timers won't magically make an application work in the background, but
they will run if an application already happens to run in the background. That's
our case while in a conference, so these timers will run, allowing XMPP pings to
be sent and the conference to stay up as long as the user desires.

Until we make a decision on access modifier hints and adopt a respective
coding style, consistency is king.

It turns out that it is not enough to give lib-jitsi-meet the room name
in lower case. BOSH also needs the room name in lower case.

The desired behavior of the button 'Start a conference' / 'Join the
conversation' is to launch the mobile app if installed; otherwise, do
nothing i.e. continue to display UnsupportedMobileBrowser.

Anyway, we may change our minds about allowing the user to continue in a
supported mobile browser so preserve the source code that enables that
but give it more appropriate naming.

React Native provides a Platform abstraction which React does not
provide.

Simplify the source code (with the idea that source code which does not
exist does not have to be maintained).

Additionally, apply modifications to have the source code comply with the coding
style.

Overall, prepare saghul:audio-mode for merge into jitsi:master.

It's fired before creating the conference with lib-jitsi-meet.

Recently, we reimplemented the watermarks in React. Unfortunately, we
didn't take into account film strip-only mode.

Additionally, we duplicated watermark-related source code on the Welcome
and Conference pages.

React Native provides Platform.

Redux actions which represent "commands" should be imperative, and those
representing events should use the past tense.
