Add 4 new bullet types.

In a way, this adds "life drain" suggested in #1 though it is mana drain instead.

This adds 4 new bullet types:

• Black hole bullets. Due to all spells being centered on a user (and not centered on an object), I had to make the spell randomly target an enemy. This applies a suction force.
• Flashbang bullets.
• Laser bullets. (+ Armor penetration)
• Mana leech bullets. Takes 5 mana to craft like the other ones, but gains you 3. You can empty a mag, cast a spell or two, reload, repeat.

Technically, this was 5, but acid was so boring I forgot about it.
