UART stuff doesn't work for some reason.

I think I've done what I need to do, but it doesn't look like the interrupt is
firing at all.

Plan for tomorrow: merge it with the GPIO and SysTick code from the led_blink,
which should let me get status info, since I can't read hardware registers from
the debugger.
