-bugfixes: upon detaching the command module the main sub was unmovable; -added overvoltage protection; -added chainguns to the command module, turrets no longer autoswitch, manual button press is necessary

Added Vanguard Command module.

Hotfix for various minor issues, changed guns in command module, they are more rapid fire, non burst mode but with some spread. Front window received a blast door, which will close in case of a breach.

Remastered the submarine with new visuals and modified interior layout. No more open decks in engineering, simplified ballast tanks, removed lots of unnecesary features. The design focus remained the same. Enjoy.

Decor update

Bugfix:
* fixed the bug that constantly toggled docking when main submarine module was selected as a navigation input source

Minor change:
*Since the crowbar opening was somehow glitched, Emergency override button to aft airlock now enables the main open/close button to function.
*Captain can now use the selector in the compartment right of the gunnery to determine which terminal steers the submarine: the main terminal in command module or aux terminal in gunnery. Upon command module detachment it goes back it's own steering input, same with the main submarine.
*Aft periscope in the command module is now accessible even if the sub parts are connected.
