PID Gain Normalization Removed

This RC removes the PID gain normalization functionlity. Unfortunately it was not working as intended, as was causing more confusion than helping.

IF YOU ARE USING THE FC GOVERNOR, AND LESS THAN 100% THROTTLE FOR SETTING THE HEADSPEED, please read on:

Based on the throttle level (RPM) used, please multiple your PID gains with the following:

Throttle Scale
100% 1.00
95% 1.11
90% 1.23
85% 1.38
80% 1.56
75% 1.78
70% 2.04

The exact equation is 1 / (Throttle * Throttle).
