[PATCH] Associate 'git gui clone' with the git:// protocol

[Petr Baudis <pasky@suse.cz>]

This MSysGit patch makes the installer register 'git gui clone'
as the Git URL protocol handler. This depends on the 'git gui clone'
functionality itself, of course - currently in the process of getting
accepted upstream (hopefully).
