Move all Etherpad's access control from Meteor to a separated [Node application](https://github.com/bigbluebutton/bbb-pads).
This new app uses [Etherpad's API](https://etherpad.org/doc/v1.8.4/#index_overview)
to create groups and manage session tokens for users to access them. Each group
represents one distinct pad at the html5 client.
- Removed locked users' access to pads: replaced readOnly pad's access with a new pad's content sharing routine
- Pad's access is now controlled by [Etherpad's API](https://etherpad.org/doc/v1.8.4/#index_overview)
- Closed captions edited content now reflects at it's live feedback
- Improved closed caption's dictation mode live feedback
- Moved all Etherpad's API control from Meteor to a separated [app](https://github.com/bigbluebutton/bbb-pads)
- Included access control both in akka-apps and bbb-pads
Add the `camera` icon in the user list for whoever is sharing,
in order to improve the understanding of who is sharing the webcam.
It is possible to enable/disable this indication in the settings.yml
Video streams can be sorted by voice floor activity in the client according to FreeSWITCH´s floor events. The feature works together with pagination, essentially giving an Last-N like experience while not disrupting too much
Made video stream sorting extensible in a way. The sorting modes for pagination and unbounded can be configured in settings.yml and new sorting modes can be added to the stream sorting util under video-provider. Inline docs explain how to do that
Changed how the stream ID attribute from video-streams collection was passed to downstream components; we had an array map that was executed every change just to map stream to cameraId, which is bizarre. So I changed the cameraId usage in downstream components to be conformat with the collection attributes and shaved off the map where it wasnt needed
Add better selectors to video-list-item container´s VoiceUser fetch
