Fix for them having a frozen face upon death
Two small fixes
Makes trays a subclass of bag.
This somewhat changes how items are placed on them, but for the better as it's more consistent with existing mechanics.
Hitting someone with the tray still scatters the contents around!  Works on nonhumans.
Placing icons on the tray still makes them show up on the tray.  Using the tray on a table now places the items onto the table, or places the tray itself if it's empty.  Robots can't lose their tray this way, I checked.
Service borgs can actually use their tray to carry things!  Trays can hold all sorts of stuff, as long as it's small...
A service borg can carry the nuke disk around.  The pinpointer does follow it correctly.
If the service borg stashes its tray module, dies, explodes, gibselfs, or is forced to stash its modules by damage, it drops all the tray's contents on the ground.

Fixes #236 (service borgs can't use trays) and #2991 (Items on food trays can't be picked up).  Didn't address #1919, the layer issue.

Fixes the "bajillion lines changed" with the maps.
Why the hell not
Travis will now automatically compile the maps in the map_test shell script.
Removed an unused variable in the shell script.
Over-eye hair improvements

-Long Over eye looked like two different hairstyles layered on top of each other when it was made, giving it a weird spiky look around the face area when seen from the side. I've completely redone the side sprites.
-Regular Over eye had inconsistent side sprites which made it look a lot longer than it should.
Re-adding missing hivelord core sprite (fix courtesy of Nerolat).
