Retrokeyboard for games

Version tested: RetroPlayer 18 alpha1 2018-02-11

It doesn't appear that the Keyboard is enabled for this core. Most games, in addition to the controller, need the keyboard to start the game

Should be fixed by #4. I'll include this in the next build.

I can see Keyboard is enabled now in the log, but they keyboard inputs don't seem to register in the core for some reason (still stuck at the 'Select Game' screen waiting for a keyboard number to be pressed). Joystick inputs are registered.
