Function keys are not working

Closed #27 too fast, function keys are still not working after b9ee437.

Do you have an easy way to test them ?

If you happen to have Battle Squadron, you need to use F5 to switch on/off 2 player mode at the main menu. Pinball Dreams / Fantasies uses function buttons for different things.

Pinball dreams selection works well here on raspbian in console... should be something else on your side.

They work on a33d65d on the same platform. Reproduced and doublechecked. I guess there's a missing piece that's present on raspbian.
