Demo Mode

[robwalch]

Loop titles and opening cutscene until player starts the game. Proposed sequence:

1. Title Screen for 5 seconds
2. Scene plays
3. Hold end of scene for 3 seconds (option to play or restart scene)
4. Fade out and return to Title

If the user selects 'start' (taps the screen/clicks/presses 'A') at any point we forward to the next step, and the game will begin after step 3.

On step 3 (or in 'Demo' mode before any user input) we show the option to play or restart.

This should make playing the game a little more enticing by showing what the game is about without requiring any user interaction.
