updated brig. It now has toggle-buttons to open, so that bots stop locking each other in there (!?), but an override lock lever that also closes it if open.

Now only the searchlight currently in use is turned on. To minimize power draw and light pollution. This took some messy wiring please don't look to closely at it.

All hail the prism!

Now four hull cameras, switchable from Nav periscope, wifi controlled.

Removed power from belly dock, added spare junction to bunks to connect to dock ad-hoc in need

Added docked-indicator in nav room

Fixed the auto-close delay on the bottom floor doors to be 1 as the others.

Added a bottom docking port, with a manual button next to Navigation, in order to dock with e.g. pirate ships.

Corrected turret mounts to be transparent to guns.

Warning: upper left turret can hit roof of sub for some reason, despite limiting the arc carefully.

Tweak firing arc limits

Addede Silent mode, switch that limits engine force to 20 %, for slower and quieter maneuvering.
