Test firmware

This is a "brown bag" release whose main purpose is to test the 
effectiveness of Richard's EC fixes for the "keyboard stops working" 
problem.

It also has a fun feature for your amusement:

ok screen-ih iselect
ok 40 30 set-scaled-resolution

(It also works with more conventional resolutions like "d# 1024 d# 768 
set-scaled-resolution", but not with resolutions larger than the 
screen's native size of 1200 x 900.)
