unloading in pre-deactivate

That's certainly a feature we should add to MacPorts base for all ports
that install a launchd plist. Ideally, we'd preserve the load state across
an upgrade. That would probably mean adding a registry table to store the
current load state, unconditionally unload on uninstall and load depending
on the information in this table on install/activate.

Patches welcome, I guess. If you'd like to work on this and need a couple
of pointers to where the relevant code is, don't hesitate to ask.
