Feature request: radiolist support

[Maarten1970]

The the player in my living room is running mpd, upmpdcli and MinimServer 2.
I can play both audio files (served by MinimServer 2) and internet radio (streams configurede in upmpdcli's radiolist). Using BubbleDS as control point (Android phone).

However in my kitchen I have a upnp/dlna compatible device so I can still play audiofiles but no radio.

It seams more logical to define the radiolist in MinimServer than in upmpdcli.

Would be nice if the radiolist functionality of upmpdcli (including the possibility of running (python) scripts to obtain metadata and album art) could be integrated in MinimServer.
