root: add template variables pointing to repository directories
These paths are useful for GUI applications to detect changes. A GUI process
typically monitors .hg and .hg/store directories so that it will be notified
on lock/wlock deletion.
Alternatively, maybe we can add debugpaths command if we don't want to extend
the root command. I'm not sure which will be nicer.
