New switches:
- -sw / -swizzle = deswizzle (and eventually reswizzle) the texture
- -be / -bigendian = create an FTEX file in big endian

PS3 FTEX's can be converted to and from .dds fine (use the -be / -bigendian option when converting .dds back to .ftex though!)
360 FTEXs should extract fine if you use the -sw / -swizzle switch when converting .ftex to .dds, luminance hasn't had deswizzling added though so that might not extract properly
