Removed old configuration files.
Updated for Minecraft 1.7.2.
Fixed blocks not correctly rendering in layer mode.
Fixed glass panes, iron bars and chests not rendering at all.
Fixed schematics not getting saved at all with specific multiblock structures.
Fixed a few possible NPEs.
Moved most block related things into the new BlockInfo class.
Schematics now use shorts/chars. This significantly reduces memory usage for large schematics.
Disabled schematic flipping (for now), rotation uses Forge's rotation API.
