Added KeepAlive Behaviour to ARCamera. Trackables are currently not kept between scenes due to their dynamic assignment to teams.
Possible fix for android devices.
Fixed duplicating ARCamera when QRCodeScene would be loaded for the second time.
Removed confusing creator from start screen
Gave rotating block on start screen a random color.
Fixed returning to QR scene when disconnected and added handling in case connection can't be established.

Minor fixes:
 - Send progress of all teams to player on join
 - Move rotating block in start screen above ARCamera
 - Do not stop ARCamera in start screen
 - Change focus mode
