Support for ScrobbleDroid / Simple Last.fm Scrobbler API

A boost in app Support, would be to add support for "ScrobbleDroids" and "Simple Last.fm Scrobllers" API
As far as I can see, a Broadcast-Receiver for each API would need to be added

API Documentation: 
[ScrobbleDroid](https://github.com/JJC1138/scrobbledroid/wiki/Developer-API)
[Simple Last.fm Scrobbler](https://github.com/tgwizard/sls/blob/master/Developer%27s%20API.md)
