BluePower computers

Includes
Blocks, TileEntities, GUI code etc for CPU, Monitor, Disk Drive, IO Expander.
Memory mapped monitor, with ability to change screen color (going to make config option).
CPU attempts to read RP2 style boot loader.
Some basic textures, can be improved by others.

Still to be done:
Replacement character set texture sheet for monitor, I'm trying to get bugs out of the UV mapping due to making it a separate texture.
Replacement bootloader, I have some ideas I'd like to implement anyway.
Front Panel DIP switch GUIs (bus ID etc)
Vast Majority of CPU instructions/testing etc.
rednet and IO Expander, waiting on bundled cabling before I can do much with either. (also can't do anything with IO Expander textures as cable output need to match.
