This file is in a rather bad state. Hence:
- remove doubled "rudder" settings
- fix & nasalify brake properties (/controls/gear/wheel[?]/brake, yet again)
- remove redundant index setting
- nasalify throttle (to allow more than 8 engines)
- nasalify flaps (to make flaps with more than 4 positions work)
- nasalify elevator trim (just for fun :-)
- fix syntax
- remove lots of trailing spaces
