Update git-gui tree please?

As Sebastian's addition of BeyondCompare-3 as a new backend for mergetool has graduated to my 'master' branch, could you fetch from me and merge the tip of ss/git-gui-mergetool branch to git-gui repository, like this?

	git fetch git://git.kernel.org/pub/scm/git/git.git next
	git branch ss/git-gui-mergetool f3768a6714e667205d68475
        git merge ss/git-gui-mergetool

Also I'll hopefully tagging 1.7.5-rc0 by the end of the month or the middle of April at the latest, so please start planning to wrap up the enhancements and fixes meant for the next release and throw me a pull request when your tree is in a good shape to do so. I realize that I am already behind your tip 4c2519e (git-gui: fetch/prune all entry appears last, 2011-02-22), but I'll wait until I hear from you.

Thanks.
