Video thumbnail toolbar fixes

feat(UI): Add UI support for camera issue detection

Device selection rework

Fix incorrect JSON file

The extension of the file modules/UI/side_pannels/chat/smileys.json
suggests that the format of the file is JSON. However, it contains
JavaScript RegExp instances which do not represent valid JSON. Such
discrepancies between file extension and format cause failures in
certain tools such as Webpack. Convert the file (both extension and
format) into a valid ES2015 module.

Updates handling links on watermarks.

When link is missing disable clicking.

Change color for tooltip

Adds raise hand toggle state.

Fixes dominant speaker and raised hand tooltips

Updates lock room

Receiving password required, marks the room as locked, but if we try to enter without password, mark it as unlocked till we receive a password required error or we successfully join.

Clears the password if user cancel attempt to enter password, as using one instance of locker for multiple attempts keeps the password.

Syncs contactlist display names with thumbnails.

Fixes hiding toolbar.

Uses the same display names in the contact list as in the thumbnails, for local and remote.

Receiving messages docks the toolbar to be able to see number of unread messages. We need to undock it when we read the messages. We skip undocking if we are not in video mode (on large), cause stuff like youtube video share is docking/undocking the toolbar.

Video thumbnails redesign

feat(ringoverlay): Stop ringing after 30s and change the message

feat(ringoverlay): Change the background when the avatar is displayed

Adds raise hand icon
