Started implementing new IPublishedMediaStore which will replace the notion of the legacy ExamineBackedMedia and

moving forward will open up many nice opportunities. This will be used for the media accessor in the new DynamicDocument.
Renamed XmlPublishedContentStore to just DefaultPublishedContentStore.
Made GetProperty an extension method for IDocument and removed from the interface as it is not needed there.
