Shield and Wing powerups work fine. Powerups fade out after being picked
up and properly lose their ability when that happens. Proper sound
effects are played.

Need to add score multiplier effects as well as correct issue where
explosion sound not heard if destroying an exploding hazard with the
Shield.
Added multiplier effects to score
Bonzo now loses his powerup on death
Bomb sound effects work properly. updated debug world contents,  and
resource packs, to account for the new explosion sound effect.
Updated .jar and readme.
