Tweaks/partially refactors small craft repair/refueling modules

About The Pull Request

This PR fixes several issues with fighter repair & refuelling modules, and fixes some bugs surrounding them.

Things changed:

Repair/refuel modules are a bit more sane now, and shouldn't arbitrarily stop fueling because of battery issues or the target not having any gas
Repair/refuel modules are a bit faster now (although they aren't quite as fast as doing things by hand)
Repair/refuel modules have a max range
Targeting has more signals
Dropship virtual z-levels are a bit more sane, and should stop making repair beams die

Why It's Good For The Game

This should hopefully make these modules more useful. Also, runtimes bad.
