KA10: Stanford Cart device

[larsbrinkhoff]

SAIL hardware device used to control the Stanford Cart.

It also doubled as an audiovisual indicator. Green light means system is running. Red+yellow means crash. Ringing bell means system is debugged.

I have three of these which does the bell nicely. But a new version with lights would be good.

I implemented a CART device. For now the only action is to log debug messages.
