Made gyp file for command buffer libraries.

Gyp build works on Windows. Mac and linux won't work yet.
Fixed some warnings.
Switched from dxerr.lib to dxerr9.lib.
Implemented a Texture::SetRect case for DXT compressed textures.
Fixed division by zero for zero stride vertex buffers.
TEST=none
BUG=none
