Thoroughly clean up the code to vastly reduce the number of compiler warnings and found and fixed several bugs in the process; Applied all mainline PCem commits; Added SCSI hard disk emulation; Commented out all unfinished machines and graphics cards; Added the AOpen AP53 and ASUS P/I-P55T2 machines as well as another Tyan 440FX machine, all three with AMI WinBIOS (patch from TheCollector1995); Added the Diamond Stealth 3D 3000 (S3 ViRGE/VX) graphics card (patch from TheCollector1995); Added the PS/2 XT IDE (AccuLogic) HDD Controller (patch from TheCollector1995); Added Microsoft/Logitech Bus Mouse emulation (patch from waltje); Overhauled the makefiles (patch from waltje); Added the Adaptec AHA-1542CF SCSI controller (patch from waltje); Added preliminary (but still unfinished) Adaptec AHA-154x SCSI controller BIOS support (patch from waltje); Added an ISABugger debugging device (patch from waltje); Added sanity checks to the Direct3D code.
