Title: GRAPHICS: Add a PCX decoder

This adds a common PCX decoder and replaces the custom decoders of the following engines:
- dreamweb
- hugo
- queen
- tucker

It does NOT replace the PCX decoder of the drascula engine, as the PCX images in this one are mangled on purpose - their header has been zeroed out. Furthermore, the videos in drascula also use the same RLE encoding, so it's not possible to remove the RLE decoder. Thus, this engine is not modified to avoid extra complexity in the engine code. Nevertheless, here's a patch for the drascula engine, for completeness:
