Moved var/force from /obj/item to /obj so that everything gets it, including structures and machines that get tossed around using Telekenesis. The default force is still 0. This should finally put a stop to a large number of runtimes.

Runtime fix for being hit by something without there being a usr. This was most likely due to explosions or possibly mass drivers.

Runtime fix for simple animals using department channels. Only parrots can use them now as they are the only simple animal with the 'ears' variable.

Runtime fix for the mech's energy relay process() when there is no battery in the mech.
