Added Armature Component and Bones.
Loads .armature files and draws the skeleton in bind pose.
Starting work on adding rotations to the bones
Bone rotations work -- for the most part.
Importing bone weight influences and passing them along to the shader.
Added a bone color shader.
Bumped up the model format version number.
Bones work! =)
Bones work in the color shader. Still a bunch of cleanup necessary.
