Small fixes for dogborgs and sprite accessories:

-Ported the hidden snippets of the dogborg code.
-Reset module now resets pixel offset and icon directory again. (broke shit when reseting from dogborg)
-Medihound belly fixed.
-Husky body marking tweaked to not overlap arms in side view.
-Added husky ears that are basically wolf ears that use secondary color instead.
