WW Model Helpers 2.2.0

• When converting textures from PNG to standalone BTI textures using one of the C4/C8/C14X2 formats, and the number of unique colors in your custom texture is too large for that format to support, the texture will now have the number of colors in it reduced automatically by the scripts during conversion instead of giving an error. (This only applies to standalone .bti files. You still need to manually reduce the number of colors for textures embedded inside models.)
• Fixed a bug where SuperBMD would not be detected even if it was in the correct location if you were running pack_models/unpack_models from a working directory that was not the folder they were in.
• Fixed Link.arc and Ship.arc INF1/JNT1 fixes not working if you use the -rarcname argument and capitalize them incorrectly.
• Some improvements to generate_previews.py to prevent crashes or give better error messages when crashing.
• Removed support for the old -link argument, use -clean instead.
