Update LED throttle mode to use rcData instead of rcThrottle, avoid

having to reference min/maxThrottle.

Range was not being calculated correctly.

Throttle color now blends with the current color of the LED so that at
mid throttle any orientation color is still correct when mixing Throttle
and Flight Mode on an LED.

Fix tabs.  Reduce nesting level.
