Fixes the spoilage timer for cannibal luncheon meat.
Prevents weird bionic weapon collision bug.

Previously if you activated your bionic blade or claws while the other
was already active (i.e. activate claws with an active blade or vice
versa) it would cause you to drop the otherwise-undroppable pseudoweapon
item you initially had equipped. This prevents that behavior while
reminding the player to deactivate their current psuedoweapon first.
Smarter code.
Even smarter code.
