Several small bugfixes

About The Pull Request

I was playing today and noticed a few bugs, they seemed easy enough to fix.

The servo_rating, capacitor_rating, and servo vars were unused for mecha UI so I removed them.

For the changes in robot_bodyparts.dm, I also chucked handle_atom_del() in the bin and moved its responsibilities to Exited() because I hate and I am preparing for its removal.

I also cleaned up some GPS code because why not.

Didnt power and surgical tools have alternative inhand sprites? I'm pretty sure that at least hand drill and laser scalpel supposed to look different in hand upon mode switch.

Also pls dont forget about cleaving saw

Not that I saw.

The cleaving saw had an in hand icon for both states, bad bug report ig. Or maybe the right/left hand variant was missing (I don't remember what hand I tested them with)

I should have mentioned that. Yeah, it was broken in one of the hands

An easy follow up PR then. I honestly probably will not do it
