// advanced movements settings are in individual controller json files
// what we do is check the status of the 'advance movement' checkbox when you enter HMD mode
// if 'advanced movement' is checked...we give you the defaults that are in the json.
// if 'advanced movement' is not checked... we override the advanced controls with basic ones.
