Bugfixes for auto fork feature

This fixes the issue of autoFork not returning the proper values when it fails a detect or is not auto.

Also removed process from constants for default as it does not have such a param but added method as that does exist for it but is not the same as process_method so for now its left defaulted to None which does not effect SB post-processing.

Oddly enough I did set my process_method to move and my tvrage fork complained about it being invalid processing method so I'm going to have to go over my own code for my SB fork as this may be a problem in other forks as well.
