First cut of UI state machine

This patch adds a first skeleton/draft of the UI state machine, with the
altimeter setting logic implemented at a basic level. It also adds a Python
script which uses GDB/MI to simulate/inject UI events on a GDB remote (i.e.
qemu-avr running the sim copy of the firmware).
