This reverts commit 76a7c7b426.

Moves local video thumb initializations where they belong in the local video constructor. Fixes a problem when there is no video device, then audio levels and gsm bars are missing. We were doing this initializations every time a video device is changed.

Removes unused variable bottomToolbarEnabled.

Removes storing avatarURL in localstorage and retrieving it.

There was a bug that the handlers for menuItem for mute and kick are added for all remote participants. When clicked multiple handlers are executed and the action will be executed for all remote participants.

Show the toolbar even if in a ring overlay.

Adds more analytics events for shortcuts, recording and shared video. Changes the way we calculate ttfm.

IE 10 does not support "window.location.origin"

Use KeyboardEvent.key if available,
match both lower and upper case letters to keep previous behaviour

KeyboardEvent is a mess.

KeyboardEvent.which gives you, in theory, a decimal representation of the key pressed.
"r" or "R" gives you 82, which is "R", you can look at KeyboardEvent.shiftKey,
but you don't have access to capslock...

Maybe you want to use numbers, but of course NumPad will not give you the same than
"normal" numbers ...

Now if you use something else than letter, for exemple "?",
on a QWERTY keyboard "/" and "?" gives you 191,
on a AZERTY keyboard "," and "?" gives you 188, so we have to stick to letters.

This was for keydown and keyup events, keypressed event return the real char
(lower "a", "/", "?", ...) but it fails in some cases

The only non broken property is KeyboardEvent.key,
but it's only supported since Chrome 51, Opera 38, and not supported by Safari

Handles the case where the remote track is with initial value of camera and no further events are received for video type changed.
