Beginning implementation of building materials and bricks
-To-do: add localization and textures (bluh)
Refactored all of the ItemBlock classes
Fixed compound ore blocks
-Were causing crashes when pick-blocked or silk-touched
-Were not working with fortune and in fact causing crashes >_>
-Were causing GL errors with NEI world tooltip as a result of a combination of how Minecraft and NEI read localization and textures from blocks that drop other IDs
-All of the above fixed now (Mojang do not break it again!)
