Add BlipBoy support - electronut labs Blip shield

ugame.py.sample included because it is not working
if frozen in the firmware at the moment.

Can you replace the stage.py with a symlink, like in all the other boards?

[ntavish]

stage.py is not a symlink because of audiopwmio instead of audioio, and also audiopwmio not having an AudioOut member (has PWMAudioOut).

I'm not sure what's the best way to resolve this at the moment, perhaps these should be supplied by ugame.py in all other board?

Sorry for a long delay, I lost track of this pull request. I think the best way to handle this is to make your own Audio class in the ugame.py, and make the "audio" variable an instance of that class instead of the Audio defined in stage.py.
