[JGIT PATCH] Added support for creating bare repositories

[Constantine Plotnikov <constantine.plotnikov@gmail.com>]

Now it is possible to create bare repositories.
The difference from normal repository creation is
that directory where repository is created might
exists and that core.bare property is set to true.
