Flintlock Weapons mod

Cleaned up item names to be less messy, fixed a minor texture issue caused by accidentally leaving a few mostly transparent pixels in the pistol texture, added a few particles for the plasma rifle, including ones that appear when it hits a mob. I did change the item names of the weapons, so I would recommend removing any of the mod's weapons from your inventory before updating. If you don't want to do that, then this update is minor enough to skip.
