[MERGE] add a hook for Branch.set_last_revision_info()

One feature of the bzr-dbus plugin is to send a D-Bus signal over the
session bus whenever the head revision of a branch changes. It
currently does this through the "set_rh" hook.
Unfortunately, the current default branch formats do not call
set_revision_history() during commits or pulls so the D-Bus signal
doesn't get sent. It seems that the set_last_revision_info() method
is now the right place to hook to detect these changes, so that's what
the attached bundle does.
I realise that there are already hooks for commit, pull, push and
uncommit, but I think this hook has value. If I add hooks to the
previous 4 operations, the plugin would need to be modified every time
a new way to modify the branch head is added. By adding a hook to the
function that actually changes the branch, things should be a lot more
