Didn't screw up the commit this time.

I made a more accurate ingnition amount, removed the hypergolic fluid in
favour of one second worth of propellant, gave hypergolics infinite
restarts, updated pressureFed status for multiple engines. The configs
are made according to my spreadsheet found here:

I also removed the useless gimbal code I left in, to save space.
