Easy audio recording and playback for MOOCs and screencasts

Hi Hakim,

I just wrapped up a plugin that I have been using for several courses the last semester. The plugin  allows to easily record and playback audio for MOOCs and screencasts. The plugin has two components: the *audio-slideshow.js* component automatically inserts audio files for each slide and fragment, the *slideshow-recorder.js* component allows easy recording of the audio files. 

Please also check out the live [demo](http://www.faculty.jacobs-university.de/agoel/audio-slideshow). 

The plugin is related to or solves issues #472, #701, #724, and #810.

Thanks a lot for providing an excellent starting point for the plugin.

Have a great day
Raj
