Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's. Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode. Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one. (QT only) Same concept as above, but applies to the Mach8 and 32 for the 8514 option as well. (QT only)
