Merged various SMC FDC67C6xx Super I/O chips into one file, re-added the UMC88xx 486 chipsets (and four machines for it) based on work by tiseno100 and my own work, various other fixes, and added quite a few machines (including the AOpen AP5VM which now works), also added the remaining ALi M6117 machine (Protech SBC with Award BIOS), and made the Intel Advanced/ATX's on-board S3 Trio64V+ work, as well as the on-board S3 Trio64/V2 of the two Compaq Presarios.
