Changes to updated version:
- Actually looked at FlyingPotato_131's code (copied some of the code); fixed the implementation of the linear/lateral/vertical motion scheme.
- Improved pitch, roll, and yaw stability when stationary.

Trying out PID controllers.
I only used the proportional function though. The other inputs resulted in some janky behaviour in previous test crafts, thus I opted to not use them here.

Trim to control local up/down.
VTOL to control local left/right.
Toggle 4 to revert back to standard Roll/Yaw controls.
De-toggle 8 to turn off all engines.

Due to my PID implementation, Trim and VTOL cannot act simultaneously. The one with higher absolute value will override the other; in cases of equivalence, the first set value will take priority. minimal movement in the direction of command can be observed, but it is simply no where near the desired output. This is due to me linking the Trim/VTOL value to desired speed and not desired thrust output. This would apply to backwards movement too, but I hard coded in an augmentation term.

Control scheme inspired by FlyingPotato_131's MAK - 26 Solar Wind Fighter-Interceptor (www.simpleplanes.com/a/1G69Jp/MAK-26-Solar-Wind-Fighter-Interceptor). I used a portion of his code calculating for the the directional speed.
Design inspired by ASBE's LOW EARTH ORBIT DEFENSE INTERCEPTOR (www.simpleplanes.com/a/zxJ60o/LOW-EARTH-ORBIT-DEFENSE-INTERCEPTOR). I completely copied the exhaust nozzles.
