FirefoxOS packaged app

[radare]

This will require making webquake work with local files instead of websockets to fetch the paks and implement touchscreen controls.

I have verified that webquake runs fine on FxOS (2.2 at least), quite fluent in Flame, so it will be a great addition to the marketplace.

@radare just run it via docker instead: https://github.com/589290/webquake-docker
