Logic

Audio stops at all game state changes.

On event BIRDS_EVENT the standard MP3 (BIRDS_AUDIO_URL) plays, repeating continuously. On event BIRDS_ALTERNATE_EVENT the alternative MP3 (BIRDS_AUDIO_ALTERNATE_URL) starts playing on next repartition, repeating continuously there after. On event BIRDS_STOP_EVENT all audio stops. On event BIRDS_PAUSE_EVENT all audio stops. On event BIRDS_RESUME_EVENT the last MP3 selected plays, repeating continuously.
