Fixes issue #129
Removed the unused /datum/bullethole
Removed some copypaste code inbetween the targets and the target stakes
Made these objects not search for eachother in the nearby turfs, they both link to eachother now
Added removeOverlays() and nullPinnedLoc() procs for /obj/item/target
Added removeTarget() and nullPinnedTarget() procs for /obj/structure/target_stake
Added a huge list of additions to the commit log that nobody will read
Cleaned up the code for both objects (target and target stakes)
