Onscreen Controller

[bspinner]

The onscreen controller isn't displayed even when activated.

edit: So, I started working on this.

• Show OnScreen Controller (OSC) with D-Pad and one Fire Button
• Enable user to enable/disable osc via Settings menu
  • Enable user to add additional fire buttons (up to 4)
• Enable user to show native keyboard for text input
• Add smaller button which shows additional "meta" buttons:
  • show Amiberry GUI, like F12 (later: stop emulation and go back to Library)
  • later: enable/disable touches for mouse input

That's on me.
The code there was designed for SDL1, so it's disabled (but still in the source files) until I rewrite it and adapt it for SDL2.
