Added Guest and Test profile types, and profile priorities so the position of a profile in the list can be controlled.  Fixes crash bug that occurs when a profile dir is renamed to a non-number and a new profile is made.
Added debug menu option for resetting key mappings to default.  Added sanity checking requirement to ScreenMapControllers.
Reset keys debug option changed to save defaults to disk and reset.
Added NoteField lua functions to allow the theme to control how the receptors and ghost arrows flash.
Function chaining for actors and singletons.
Function chaining for PlayerOptions and SongOptions APIs.
