Failsafe modification

The following protocols are supporting failsafe: FrSkyX, Devo, WK2x01, SFHSS, HISKY/HK310 and AFHDS2A
In Serial mode failsafe is configured on the radio itself.
In PPM mode and only after the module is up and fully operational, press the bind button for at least 5sec to send the current stick positions as failsafe to the RX.
