Auth content uploads. Added a mapping function from request > filename. Added exception handling for content uploads. webclient: Only prefix the client API path on doRequest, not doBaseRequest (this would've broken the identity server auth too). Added matrixService.uploadContent. May not require mFileUpload anymore.

Do not start the event stream if the user is not logged in (=if he does not has an access token yet)
Add isUserLoggedIn to check this.

Remove old polling stuff from RoomController. Added service comments. Do not start the event stream on startup unless you have credentials.

Added event stream service which neatly blobs together requests / state for the event stream. This depends on matrix service to do the actual hit. Currently this has exactly the same behaviour as before.

webclient: You can now paginate in rooms. Defaults to 10 messages, with a button to get more (needs to be hooked into infini-scrolling).

Move the unknown token broadcast to the interceptor. Return the $http promise and not a wrapped one via $q. Everything now needs a level deeper nesting. Fixed registration and login.

add in copyrights to everything, not just the synapse subdir, and add a copyrighter.pl whilst we're at it
