Fix more things

CPU Disconnects devices on break
TileDevice tracks attached state
Typo in GuiCPU

Also I have no Idea what I'm doing. This is most likely going to sit on
hiatus until Bundled Wires are implemented (For Ribbon Cable) and until
someone developes a proper interface to connect and disconnect Devices
to the CPU. I also need to make an actual renderer for the Display, Disk
Drives, Disks, Backplane's, and Memory to sit in the Backplane's.

*sigh*
