Moving a naming convention more consistent with the Forge naming convention.
I'm just following what I was told on #minecraftforge.
Renamed various files to make them more consistent with the new project.

Started the drilled hole block using a bunch of placeholder stuff.  Started
to deal with the metadata necessary to track drilling vs gunpowder vs
clay vs lit.  Doesn't look like the initial metadata is setting
DRILLED_ONLY.  Need to investigate and step through the sequence.
