Submitting a new contribution now properly closes the window and refreshes the view
Implemented editing of existing idea contents (with doubleclick on the content)
When writing comments, new comments are initialized with username "You"
this fixes the issue that when submitting new comments, no username was set.
Login got a complete overhaul
* login model now also ready for upcoming api changes
* login after registration still not working, but uncommenting after the server works, will do the trick
* commentView checked deprecated user model -> fixed
* head_login template reads user model now, not only user's email address
