Updated vehicle labels to "EINSCHLAG Qualle | ESG Q1"

Replaced manual generator start crank with a manual dynamo that can be used to start the generator even when all batteries are empty. The dynamo has the added benefit of being able to supply the submarine with minimal power even if the fuel tanks and all batteries are empty.

Small QOL improvements:

- Some color changes for instruments and equipment
- Compass now has backlight when Main Systems are enabled, not only when the Submarine Propulsion System is enabled
- Changed one of the cabin underwater welding torches to a normal welding torch so that more things can be repaired in dry situations
- Replaced the auxiliary pump button with a key

Added missing liquid valve to one of the automatic bilge pumps that could lead to cabin air and pressure loss

Updated coloring (equipment)

Updated coloring (equipment and added color variations to hull)

Improved the generator by adding overheating protection, reducing the noise. This leads to a bit less generator output, while also reducing the RPS and therefore the fuel required.

Increased generator output

Increased top speed (submerged & surfaced) and improved pitch stability
