Updated MixerCurveWidget so that it can have ranges other than 0 to 1.

Browse Source 
Default behaviour not changed.
New functions allow the setting of the max and min values for the curve.
0 to 1 range is needed when output is used for motors.
-1 to 1 range is needed when output is used for a servo.
