Merge pull request #1 from TUD-KP-WebCall/development

Development
+ WebRTC.js.coffee:
Added class Channel which establishes Publish/Subscriber connections of Faye on client side.
Each Channel should be constructed with a route as parameter (e.g. /meetings/1). Listeners can be added via channel.subscribe and removed via channel.unsubscribe. Messages/data can be published via channel.publish. All Faye internals are handled in this class, even a singleton-like client connection to the server is available as Channel.Client (in this case Channel must not be an instance variable - it's a class variable.
[WEB-17] added user model for authentication and creation of users
[WEB-17]
o meeting.rb – validation modified
o meetings_controller.rb – authentication added
[WEB-17]
o _form.html.erb – removed isParticipating property because it is not required when creating a new meeting
o _meetings_controller.rb – authentication disabled to make further development easier
