Compatibility with the last patch
- Railgun shells are now stored more efficiently horizontally
- Railgun hatch now has a platform that still lets shell pass through, making the sub more AI friendly.
- Railgun autoloader room is now more compact leaving more room for engineering storage.

NEW features
- Long range alien lifeform scanner, informs you of Alien presence in multiple sectors around the ship
- Battery docks charge with a sequence to save power. Plug your battery, press the button to lauch the charging sequence and it will stop draining power once the battery is fully charged.
- Real parallel power grid. As a result it is slightly unstable during big change of load. Use the batteries to flatten the consumption.
- Junction boxes do not decay on their own anymore, they have to be in use or underwater to be damaged. The unstability of the grid create small overload regularly that create a natural decay.
- Junction boxes overload sensitivity slightly increased to create the decay.

Feedbaks and tuto:
- Buttons mouseover messages customized to explain their use
- Submarine description added in a logbook placed in the captain safe.

Various Fixes:
- Rear coilgun base rotation fixed
- Objects depth
- Interactions removed from scenery objects

Minor fixes

Front part design rework:
- You don't have to pass through the armory to get to the medbay anymore
- Command post now has 3 floors instead of 2 to avoid being flushed when the glass is broken.

New feature: stealth speed.
Can be activated by a button next to the nav terminal, clamp engine power to 25 so they emit no sound.
Note: there is a bug, you have to go bellow 20% then go back to 25% to make the sound disapear.
Combined with a shutdown reactor the ship emits absolutely no sound and can still achieve a speed of 10kmh.
Very usefull to bypass blind enemies like Molocs. Remember that running, rapairing or dropping something on the floor also emits noise !
