Changeset 7504

Message:

Pickups module is now (from what I can tell after some basic testing) fully functional over the network.
However it's still a little messy, needs some cleanup and documentation.
I introduced a new class, the PickupListener, which allows reacting to pickups becoming used, unused, picked up or dropped.
