[PATCH cogito] adds cg-mirror-add and cg-mirror-sync

The attached patch adds the two programs cg-mirror-add and
cg-mirror-sync.  Say you do all of your work on your laptop and you want
to make a mirror of your repository available to the public.  You
specify the location of the mirror with cg-mirror-add:

$ cg-mirror-add scp://my.server:/var/www/repos/project.git

which locally creates the file .git/mirrors.  When you want to upload
your changes, you run cg-mirror-sync.
