Adding upmpdcli as a client for Logitech Media Server

[hkphantomgtr]

It was using MAFA in my android phone.  I think it's a very good MPD client after all these years.  It's worth to buy.

Thank you for your suggestion. I have purchased MAFA and it is better than MPDroid, which I was using in the past.

Going to MAFA brought back unpleasant memories of how frustrating Mpd was with its limited album art management. But otherwise, MAFA is running well.  

I put a cover.jpg in every album folder.  It works fine with different mpd apps for many years.
