cleanup: Disconnect all signals on objects
This is not strictly needed because we don't have objects with multiple references around, but it's still something nice to do, so disconnect when we don't need an object anymore.
Due to an influx of spam, we have had to impose restrictions on new accounts. Please see this wiki page for instructions on how to get full permissions. Sorry for the inconvenience.
