Highly unstable build, contains a lot of test/messy code!
Closes #11, partially fixes #13 (still required the addition to the config file), fixes #22.

Refactored a lot of things around, not done yet though.
BlockInfo is the place for mod integration, I'll be adding other mods' blocks to those lists, once I have a few in anyone is free to contribute.
Finally nuked the kinda broken properties/config files (integrated into BlockInfo, still needs dynamic config write/read - testing code is present and working).
Blocks and metadata now use shorts/chars. This significantly reduces memory usage with large schematics (down to 40% the original amount).
SchematicWorlds are now read using the SchematicFormat classes. Separating world related things and loading for cleaner classes.
Schematic flipping is disabled for now (it may come back at a later time, it may done). Rotation uses the ForgeRotation API.
KEY_I has experimental code for the improved printer (this is not the importer!).
