feat(gitconnect): Changes in communiction between gitconnect and gitpull ctrl

- The gitconnect ctrl sends now a message and $rootScope when the connect to git or github was successful
- The gitpull providers realize now, when a connection to git was made
  and shows the pull button only, when the provider is git
refact(contentctrl): Just removed a unneccessary console output
feat(contentedit): Changes how editcontentctrl checks if page can edited

The controller checks now not only if the user is authenticated.
It checks also on which route the user is and if it can edited.
The search page and also the git connect page can't be edited
