Remember the repo that is cloned from during branch/checkout/edit

We do this by storing a morph.repository option in the local clone's
.git/config file. This way the user can rename local repositories or
move them around in a system branch in whatever way he or she likes
and we can still find the repository later by the same name.

Previously, we could only identify repositories in a system branch
by their directory name. Now things are more flexible and tolerant
of "unexpected" user behavior.
