[PATCH] topgit tg push feature

[Marc Weber <marco-oweber@gmx.de>]

The patch should apply cleanly on 9f685cd79.
Or fetch it from branch t/tg-push at git://mawercer.de/topGit

Until now you've had two choices:

git push --all # pushing all top-bases and all other branches
or run
git push t/foo top-bases/foo # + all deps manually

tg push allows you to
a) push branch and its base, the branch you're on is used
b) push branch its deps and their bases (adding -r)

using tg push remoteA remoteB you can push to multiple remote locations.
