Working AV implementation

[njsfield]

Steps

• [x] Make server certs
• [x] Install tls settings for Hapi to enable certs
• [x] Load AV module in main.hbs
• [x] Make instance of new AV module in app.js
• [x] Connect callback functions to WebRTC instance (to attach video streams to)
• [x] On tab click, call 'update permissions' to update permissions to av. #84
• [x] On reply, if server allows permissions (and other 'av' user in room) then start WebRTC
• [x] If not allowed, display message in video pane ('Not allowed')
• [x] On hang up, call other permissions update to return permissions to 'chat'

For on reply -

If endpoints.length == 2
  myAV.addMyMediaStreamToVideo(myvideo)
  // here figure out the peer endpoint in the array, by is NOT myComms.endpoint
  myAv.callEndpoint(peerendpoint)...
