Dev-Freeze fixes

* Fixes #6123
* Reduces SM charging rate and increases output a bit. It should now be possible to start the engine without varedits. The engine layout still needs to be changed but I'm not sure what the best starting layout would be yet, and I'd rather not make any mapping changes until the borken areas in security are fixed.
* I also plan to adjust the air canister ```filled``` values to get airlocks to cycle faster, but again, not going to do any mapping changes yet.
