Rygel Open Source DLNA Media Server Adds PV Subtitle Support to All Resources

Rygel 0.27.4 improves the MediaResource copy constructor so that it is capable of copying import_uri, correctly serializes import URI in MediaResource, and adds PV subtitle support to all resources. Furthermore, rewriting of the subtitle URIs in the PV tag has been fixed in the server part of the software, and some issues with Vala dependencies have been addressed in the database part, which has been made a little more generic.
