Added the IBM 5161 ISA expansion for PC and XT;
Cleaned up the parallel port emulation, added IRQ support, and made enabling/disabling per port;
Added the Award 430NX and the Intel Classic/PCI (Alfredo, 420TX);
Finished the 586MC1;
Added 8087 emulation;
Moved Cyrix 6x86'es to the Dev branch;
Sanitized/cleaned up memregs.c/h and intel.c/h;
Split the chipsets from machines and sanitized Port 92 emulation;
Added support for the 15bpp mode to the Compaq ATI 28800;
Moved the MR 386DX and 486 machines to the Dev branch;
Ported the new dynamic recompiler from PCem, but it remains in Dev branch until after v2.00;
Ported the new timer code from PCem;
Cleaned up the CPU table of unused stuff and better optimized its structure;
