code cleanup

added "Active Nacelles" and "Flight Mode" to the display.

if a nacelle has no engines or its rotor is detached, it will no longer be used for the flight model.

updated description of speedLimit

more cleaning of the code

also, made drift a little more reliable. and it should be decreased in most cases

done some general clean-up and simplification of the code

fixed bug where cockpit had to be placed in the -blue direction. now your cockpit can be facing any direction you like!

gone back to hard-coded thrust values because the other system didnt work very well. it is now a fall-back for modded thrusters (or large ship thrusters)

fixed bug where thrusters would error and not produce thrust even though they are on.
this is a quick fix, ill get to the core of the issue later once i have finished overhauling the system.

support for all thrusters that contain the string "Thrust" in the subtypeID. if a modded thruster does not work, contact the mod creator.

thrust now corrects for the thrusters decreased power in atmosphere (or atmosphere thrusters at altitude)

fixed bug where craft would slowly drift upwards.

fixed for update

noticed bug: placing the cockpit in any orientation other than backwards from default will result in the controls being wrong.
