Android: Multiple changes

- Fix game list display of NTSC-J region
 - Hook up quick load/save/reset options in emulation view.
 - Add speed limiter toggle to emulation view.
 - Add game list scanning options to main menu.
 - Add resume button (not yet hooked up to save states, it'll start the
   BIOS shell)
