Mining Fixes

- Adds fire delay to kinetic accelerator and energy crossbow to prevent
an exploit that allowed rapid firing. This doesn't happen on -tg-'s
code, and the kinetic accelerators and ebow code are identical, so I'm
going to assume our gun code is to blame.
- Few mapping fixes on the asteroid to make sure the conveyor near the
northern mining outpost is powered, and that said outpost is no longer
open on its left side.
