Fix notification about network issues not displayed when expected

Fixes moderator related elements when everyone is moderator

fix(FilmStrip): Add check for thumbnails

rise-hand-ico: blured class added

Changes the state of room locker if room was locked not by current user.

Invite to share dialog

Makes sure we always resolve(call the callback) in feedback dialog.

Call the callback even when clicking outside the dialog, or escaping to close it.

Adds close page

When enabled after hanging up redirect to close page, if needed feedback will be displayed.

Moves handling of thank you dialog out of the Promise that handles the feedback and just before we redirect to welcome page.

fix(ringoverlay): Path of the ogg file

fix: remove Prezi leftovers

The message about having connectivity issues should be displayed only
on top of the video like the "video problems filter" is.

Only the VideoContainer is interested in showing the video problems
filter which is meant to be displayed when ICE is disconnected.

Always show number of participants badge in toolbar.

Includes showing 1 when user is alone in the room.

disable_star_indicator added

fix(toolbar): Issue with toolbar is positioned under the ring overlay

Small videolayout refactoring

It is confusing when the name of the main class exported from the file
is not the same as the filename.

VideoContainer is a separate being which implements the LargeContainer
and it's confusing to have it in the same file. This was encouraging to
access private parts of the VideoContainer directly(not through
the interface).

Moves the number in the code, not as a translation parameter.
