[Merge] lp:~justinmcp/qtubuntu-media/metadata into lp:qtubuntu-media

[Jim Hodapp]

Review: Disapprove

I just removed the MetadataReaderControl implementation and everything associated with it. Instead, a rather large project of finishing the metadata interface in media-hub is needed (not saying you have to do that work). I'm curious what you are using the MetadataReaderControl interface for in Oxide?
