Add parameters for list of modes bound to rc switch

Parameters: CTL_FLT_MODE_0, CTL_FLT_MODE_1, CTL_FLT_MODE_2.
Also fix a bug with incorrect choosing the mode from controlMode.

@@ -143,6 +143,8 @@ If using brushless motors and ESCs:
 1. Set the appropriate PWM using the parameters: `MOT_PWM_STOP`, `MOT_PWM_MIN`, and `MOT_PWM_MAX` (1000, 1000, and 2000 is typical).
 2. Decrease the PWM frequency using the `MOT_PWM_FREQ` parameter (400 is typical).
 
+Reboot the drone to apply the changes.

 > **Remove the props when configuring the motors!** If improperly configured, you may not be able to stop them.
