*Adding maracas. Hold CTRL and move in all directions to shake them like Cuban Pete!
*Added a pair of maracas to the Party supply crate
*Awarding a pair of maracas to those who outbomb Cuban Pete
Sadly the maracas only make noise when you use the actual "eastface", "southface" verbs. which means that you have to hold down CTRL. But oh well, I guess I'll remove that and let players figure it out.
