Fixed reactor not properly working with new top docking port circuitry and added an extra diving suit to properly support five players as advertised in the description.

- Added reactor temperature and battery charge percentage information to Command Room.
- Added extra id cards with full authorization to Armory.
- Now the top docking hatch gives power to docked subs, unless it receives power in which case it considers it a station thus drawing power and shutting down the reactor as before.

Just updated the preview image, no changes done to the sub files.

Moved the ventral coilgun a bit to the front to better fit shuttles on lower docking port and to encourage the use of depth charges when enemies are near dorsal tail.
Also, now the oxygen generator deactivates when the reactor shutdowns. Oxygen bottles may still be recharged on their shelves.
