Upcoming moOde 6.4.0 update

[grasshopper]

@Malefoda I just updated two players, all is ok now, but after the reboot I spotted the mpd error both times. I went straight to the library options and chose to sort them by year, an update I've been looking forward to. My playlist and list of queued music vanished, as did the library. I just updated the mpd library and deleted the library tag cache, both players now see all music and sorted by year :-) I didn't touch mount options, I suspected this was caused by the change of mpd versions?
Sounds great btw.
