Reworked a few things and re-implemented memory write protection in the SCAT emulation, to require less unusual mappings;
Removed two files that should not be there;
Made sure all graphics cards' memory mappings are mapped as MEM_MAPPING_EXTERNAL;
Added MEM_MAPPING_ROMCS flag to signal that a mapping responds to MEMCS* and made the BIOS and Intel flash mappings use it.
