Big Update to the Hammerhead C version! If the changes get a positivie feedback, they will be extended to RFR and XP variants aswell.

Added a "turbo" function: with 4 new additional engines strapped to the vessel, now captains can get a quick increase of the vessel's horizontal speed by pressing the "boost" button in the navigation terminal.
The boost direction (forward or backwards) is dictated by the current nav terminal direction and it has a long cooldown, use it wisely

- added a boost meter on the nav terminal
- decreased the power of the main engine by 100 to offset the new boost mechanic
- moved the arc-coils toggle button away from it's original position, now it's a lever on the nav terminal itself
- tweaked the AI pathing so they should not get stuck in the oxygen compartment anymore
- moved most of the wiring components in one place to have less clutter around the walls of the sub
- moved the top coilgun near the docking hatch to let creatures have a bit more fun when hugging the command room glass window
- general fixes to the "can't dock to null" error
- tweaked the camera drone hulls
- made the stair ramps "fancier"
- minor textures changes

-altered camera drone's logic so the "can't dock to null" error can no longer appear at the start of a round
