Added emulation of Cardex ET4000/W32p with ICS/SDAC RAMDAC;

Browse Source 
Fixed ET4000/W32p clock (for non-Diamond variants) and banking extension;
Brought the code on par with the mainline;
Fixed names of the two Cardex ET4000/W32p variants per the BIOS'es;
Brought ET4000AX unknown RAMDAC back in line with the mainline (reverted bogus "fix" by Win9xFan);
Made 15bpp and 16bpp colors more accurate.
