Exploding Fireball, Chain Fireball

Again, screenshots don't really capture it, but I've added two new spells, so the mage character is now totally overpowered.

• Exploding fireball - as a normal fireball, does one point of damage to the targeted enemy. But then, it splashes additional damage to all adjacent enemies.
• Chain fireball - inspired by chain lightning in any number of other games, the fireball does 2 points of damage, and then up to three subsidiary fireballs are spawned, forking off towards other enemies, up to 4 hexes away. This repeats for a chain of possibly 3 levels deep.

I added a single new animation class that accomplishes both of these effects, it's just a matter of seeding it with the appropriate data.

However, I'm not entirely certain that the chain fireball does the right thing - it's fiddly, and there are angles and whatnot, and maybe I'm doing something wrong. Still, it's nice when it works.

I've got a little over 10 hours to create a final level, the throne room of the Rat King, and maybe even make the Rat King a custom AI.

And I might give myself some slack and slop over into January 1st.
