git-gui: Add support for adding remotes
When a remote is being added, it can also be automatically either fetched
or initialized and pushed; this patch adds capability for initializing
of local and ssh repositories. This also of course leaves a lot of space
for further customization features, like individually turning the
initialization phase on/off or tuning attributes of the remote
repository; I consider that out of scope of this patch, however.
