Code cleanup. Probably about 40% through.

Moving blocks and items to their own classes. There is just way too
many, and my main mod class was becoming stupidly large.
I don't think this will effect speed at all (maybe 0.0001 TPS?) but it
makes me happy!

Tomorrow, I want to get Akatoe a bit more interesting. Who knows, maybe
I'll stick Remula on the mod server and let people build me some
Akatonian villages ;)
