Interrupt OsuParser by pressing 'ESC' in Splash state.

Allows parsing only a subset of OsuFiles, in case parsing takes too long.

Other changes:
- Press 'ESC' three times to exit from the Splash state.
- Override Container.exit().
- Reset MusicController in closeRequested() to prevent an OpenAL error.
