removed the throttle min max settings for user config. 

turned off altitude interpolation for now.
removed the "Dampener" setting in config. Using less confusing kD instead.
removed throttle_cruise reset in events.pde for RTL - would cause a crash.
added I term for pitch/roll for when flying greater than 20°

// Throttle control
//
// THROTTLE_MIN OPTIONAL
//
// The minimum throttle setting to which the autopilot will reduce the
// throttle while descending. The default is zero, which is
// suitable for aircraft with a steady power-off glide. Increase this
// value if your aircraft needs throttle to maintain a stable descent in
// level flight.
//
// THROTTLE_CRUISE OPTIONAL
//
// The approximate throttle setting to achieve AIRSPEED_CRUISE in level flight.
// The default is 45%, which is reasonable for a modestly powered aircraft.
//
// THROTTLE_MAX OPTIONAL
//
// The maximum throttle setting the autopilot will apply. The default is 75%.
// Reduce this value if your aicraft is overpowered, or has complex flight
// characteristics at high throttle settings.
//
//#define THROTTLE_MIN 0
