The $playMode store manages the play mode for the app. It can have the values:

• 'continue' (to next chapter)
• 'stop' (at the end of the chapter)
• 'repeatPage'
• 'repeastSelection'

Add an event handler when the playing gets to the end of the page. If the $playMode === 'continue', then move the reference forward (see what the next button does in the AudioBar).

You will need to prevent going to the next book if config.mainFeatures['audio-goto-next-book'] === false
