[SU2] Brake Pressure stuck and other bugs

[liz3]

* When spawning in C&D using the A400M and going through the power up process normally, after starting the engines and removing the Chocks the Brake pressure is stuck at 1.9 on each side. There seams to be no way to solve this other then to use Panel States: Ready for takeoff. I do not have isolated what causes this. Switching around hydraulics, warping to other stands or so does nothing.

* When toggling Panel State: Ready for Takeoff after the APU was started, the APU ignition button(the lower one) will be stuck on "Avail" while the Master switch becomes unusable.

* After using Panel State: Ready for Takeoff from actual Cold & Dark the HUD is blue rather then green.
