Routed logging through to services to support debugging.
Fixed NullReferenceException in SenderMetadata when sender's metadata does
not have an artwork URI.
Some additional checks for bad devices returning bad XML for sender
metadata. This will mean a badly behaved device will not crash UI.
fix #294 - moved BrowseMediaEndpoint project out of ohTopology.sln into ohTopologyWindows.sln
Merge branch 'master' of core.linn.co.uk:/home/git/ohTopology
