Another pit stop

Making start on pit illumination, switches etc. Tweaks made to the current pit geometry has made an impressive performance boost. Very pleased.

Let there be lights. And working switches...

Yes, even the APU cover flips up. Next, send cockpit switch messages to the TAvioncs class so systems can begin talking to each other. And I need to restore the cockpit state based on the helicopter state class. I expect I've got a few to add to that one lol. Not touched the TState class in months.
