Update 6

Update:

• Added 10 new barrels.
• Added 4 new grips. 
• Added new Skeleton enemy.
• Added new Fairy enemy.
• Changed bullet sparks effect (when hitting walls) to an shrinking, animated object.
• Fixed a bug where enemies wouldn't turn blue when freezed/slowed
• Rebalanced Part Drop Rates so that they drop more consistently, and less randomly.
• Moved the Shop onto the left side of the screen since it was hard to see on the right with larger mags.
