Add git module

[manparvesh]

Feature description:

• Save credentials to make it convenient for the user
• Know status of all the git repos (pretty display of git commits, I remember seeing a github repo for that)
• Agenda (show all the repos worked on in the past and suggest which ones should be worked on depending on code coverage etc) (creating a roadmap, basically)
• Push all (or something similar with which the day's work can be automatically pushed to remote host)
