IO port reference for common PC/XT/AT hardware

A handy reference for CGA/EGA/VGA palettes

I've also started documenting the EGA register file, since I've been all up in the EGA recently.

An EGA-specific reference will be handy as if you've ever wanted to emulate an EGA you often find yourself sorting through VGA references and removing all the VGA specific bits.
