Internal URL handling enhancements

[askvictor]

It seems that the plugin handles URLs within squeezebox in the format googlemusic:track:IDOFTHETRACK

I've written an android app to allow flinging from the Android Google Play app to a Squeezebox (see https://github.com/askvictor/SendToSqueezebox ) but it does this by converting the URL that Play Music provides into one that Squeezebox (and its plugins) can understand. Currently, this plugin seems to only handle a single-track URL. It would be nice to be able to fling an album or radio station URL across to the Squeezebox, but the plugin would need to support these URLs

Having looked at the code more closely, it looks like there is support for album, artist and station (among others). I haven't worked out if these are directly summon-able from outside though.
