Generic git support

[jgadsden]

Describe what problem your feature request solves:
Not everyone uses github or bitbucket for git repo access, it would be good to provide for these organizations

Describe the solution you'd like:
Provide support for git, not specific to github or bitbucket

Additional context:
@mikkolehtisalo reports "the application has capability to save into github. However configuring internal git that is not github would require code changes. More generic git support would be super."
