First four channels fixed

When this option is enabled, then channel grouping will not occur on the first four channels. If the channel order is AETR, then the wizard will create a model suited to the SRx stabilized receivers. For example, a model with 2 Ailerons, 1 Elevator, 1 Motor, 1 Rudder and 2 Flaps will be created with a channel order of AETRAFF. If this option is not enabled, the channel order would be AAETRFF.
