Fix #7313, formatting

Created by: dylanstrategie

• Use forceMove() instead of manually adjusting loc, fixes #7313 (closed)
• A mob eye adjustment was removed along the way, since it's also handled by forceMove()

Other changes :

• Tons of formatting, removing a bunch of useless "else return" segments (implicit in DM language, if not in all major coding languages), macros, \the, bit of comment formatting
• Squash item check slightly. No need to check that it isn't a mob before checking if it's an item, since it's an exception before the rest of the code
