convert/mtn: Add support for closing branches during conversion from monotone

Monotone treats branch closing ("suspending") in a similar manner to how we do
in mercurial - a cert is added to a revision that marks the branch to be hidden.
If a subsequent commit is made, the branch is effectively reopened.
