Procs
Attackby	wrapper proc for /atom/proc/attackby so that signals are always sent. Call this, but do not override it.

Crossed	called when atom AM crosses onto where this atom is
Entered	called when atom AM enters the contents of this atom
MouseDrop	Override mouse_drop instead of this. Call this instead of mouse_drop, but you probably shouldn't!
