Removed blaze rod and feather from KnockbackSnowballLogic. Feather will become another fly modifier, possibly feather-falling like effect. Blaze Rod is much more interesting as a fireball-launching magic wand.
ProjectileSnowballLogic modified to fire egg, XP-bottle, or fireball projectiles. The fireballs are from blaze rod (best) or firework charge (weaker yield). They can be boosted by power boosts, and really require speed boosts because fireballs twist and go other directions by nature. Boost power and they set fires too. Like arrows, if you have serious speed boost on tap these become very nice weapons.
