Description

WB performance need to be improved:

1. Currently all WB actions are passed to the server via AJAX, this blocks page for all room attendees, need to be switched to WebSockets
   1. Additionally there should be the way to split huge objects
2. Room animated pointer can pollute WB as displayed at attached image
   1. Animated pointer should be enabled only if "Questions" are enabled for the room
   2. "Animated" click should be limited (by timeout or be active count)
