Use guigfx.library for 8-bit image quantization
This achieves speed-up on OS3/68k platforms where 8-bit modes are more likely to be used, at the expense of lower quality quantization than the former picture.datatype abuse provided.
Additionally, caching of BitMaps in palette-mapped modes is now possible.
NetSurf now requires guigfx.library (and render.library) in order to start, even on OS4.
