Git: Remove gitorious code



Gitorious has changed their APIs a while ago and nobody seems to have
noticed. The only bug report I got was from Christian who tests Creator
regularly. So the code seems to be unused, which I find not surprising
considering the limited popularity of gitorious nowadays.

Task-number: QTCREATORBUG-12858
