* Add repeat option to audioservice
The audioservice.play() method now accepts a repeat parameter. If this
parameter is True the playlist passed to the audio service will be
repeated.
* Add repeat support to vlc
* Add the repeat parameter to all services
Not functional but playback will work at least. Hacktoberfest?
* Handle stop correctly in the audio service.
This allows for example the news skill playback to be stopped without
the listening being triggered.
* Handle case where service stops at end of playlist
- Fix issue when receiving multiple stop signals
- Stop method of services now returns True or False depending on if audio was playing
