Subject: [PATCH] Implant Terminals:

Implant terminals (mech) are now properly mountable and implant terminals (interface) are also properly interactive.  Player can select to equip or to remove implants properly.

Mountable:

Vehicles and implant terminal mechs now use common Mountable logic.

home3 Hart C:

All doors, save for those to the shuttle, and all implant terminals in this building are now rigged to operate.
