One can now:
- checkout an existing branch with M-x git-change-branch
- create and checkout a new branch with C-u M-x git-change-branch
- do all this from the Git menu
---
It could also be interesting to add some key biding for those
Also one might want to update the *git-status* buffer after checkout,
but this is not done by this patch
