Mike Brady 86b6d7bfff Squashed commit of the following: 
Fix Issue #890 -- https://github.com/mikebrady/shairport-sync/issues/890
    Recognise situation where a track has no artwork properly.
    Less likely to drop the 'availabile' property.
    Always output the full metadata whenever any part of it has changed.
    Metadata coming from dacp is now incorporated,
