Added headerless CIF file dimensions.
Added headerless CIF file dimensions.

Certain CIF images, like some IMG files, have no header data, so they
should be hardcoded. I would like to take all of the asset loading data
in the TextureManager and split it into individual classes for each file
(i.e., CFAFile, CIFFile, DFAFile, etc.), with some static classes for
sharing common algorithms (like decompression).
