Allow for force pushed after a rebase.

When I'm developing a new feature for a forked github repo, I will often need to rebase my branch when the main repo gets updated so to keep my branch uptodate.

Once I've made the rebase, I need to push it to my repo.

Currently, there is no push -f option and I have to run from it from the Terminal.

That works, but the terminal doesn't know about my username/password for my repo and I have to re-enter it. Which is another pain.

Richard Quadling.
