Add virtual navigation buttons to game launcher

Browse Source 
- Display < PREV and NEXT > buttons at bottom of screen when multiple pages exist
- Buttons are touchable and respond to taps
- Button dimensions: 150x40 at y=235
- PREV button: x=30, NEXT button: x=200
- Updated instructions to show 'Touch buttons or KEY0/KEY1'
- Both KEY0/KEY1 and touch button presses navigate pages
- Updated lib/ and emulator/ versions
