Add native objects and bridge menu to playback

Browse Source 
- NativeFunctionFactory resolves script method calls to native Java
  methods via reflection; VsmxNativeFunction wraps them for the VM.
- Native objects: Controller, MoviePlayer, Resource, Math, Timer,
  GlobalVariables, decoupled from the UI via a MenuHost interface.
- BaseNativeObject.callCallback invokes script callbacks like onAutoPlay.
- CLI 'rco' now wires the full menu and executes onAutoPlay headlessly.
- Validated against Batman Begins: onAutoPlay computes stream IDs and
  issues play(playList=3, chapter=1, video=0xE000, audio=0xBD00,
  audioFlag=1, subtitle=-1, subtitleFlag=0) — the anti-piracy warning
  clip with English video/audio.
