dannye 4452acb021 Fix object constant names 
swap LEFT and RIGHT
FACE is better named STAY because sprites that have no range do not
necessarily face any direction
STAY has been renamed to NONE because sprites that use this will
spin randomly, except for the item/voltorb/electrode sprite

I never should have listened to https://github.com/iimarckus/pokered/issues/89
