Move miscellaneous files to resources

Re-styles range inputs for Chrome and FF.

When rendering using a for loop each child whould have a key prop.

This solves the issue of view clipping on Android, plus it seems to be the RN
convention unless the views are very large and memory hungry.

doc: fix markdown link syntax in mobile docs

Fixes an issue where immersive mode would be enabled when coming back from the
background on the welcome screen.

Re-fixes c57e713, which was not correct.

It doesn't work properly and gives a very bad user experience. Disble it until
all underlying issues in react-native-webrtc are ironed out.

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.

The mobile app remembers the domain which hosted the last conference. If
the user specified a full URL first and specified a room name only the
second time, it was not obvious that the second conference would be
hosted on the domain of the first conference.

Now that Apple have approved build 1.2.199 for release in the App Store,
the short app version needs to be incremented; otherwise, no new builds
can be uploaded to TestFlight and, respectively, for release in the App
Store.

Fixes manual triggered tooltips text and no hover.

cleanup: remove adaptive las N config option

The feature has been replaced so the option no longer applies.

Looks like Android gets confused as to what surface to blit when we hide or
show toolbars. Setting a border on the container, seems to force the entire
area to blit properly.

Other attempted approaches, with no success:
- zIndex of -100
- width and height of 0
- opacity of 0 and setting 'disabled' on touch containers

This patch applies the workaround in the welcome page and conference containers.

Uses tooltip to show custom popups for mute mic button.

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.

Recently expose-loader broke us when it updated from 0.7.1 to 0.7.2 and
we decided to stick to exact versions.
