[PATCH (GIT-GUI)] git-gui: Support more git version notations.

[Alexander Gavrilov <angavrilov@gmail.com>]

Recently the msysgit repository has got a '1.6.1-msysgit1'
tag, which, when used to build the git version, is not
handled gracefully by the git-gui version code.

This patch changes the regular expressions to fix it, and
removes the hardcoded 'rc' string. Now git-gui can accept
a version tail like '.foo123.GIT.bar.456.7.g89ab'
