Set up database level paging for retrieving child content for list view
Amends to generated SQL pre-paging to ensure only the latest content versions are returned
Moved list view filter to repository, so can be applied with a database query
Moved list view no results message into table body as otherwise if you apply a filter that returns no results, you can't clear it again
Prevented list view filter box from setting dirty flag on form.  Without this you get the save changes warning after using the filter, but there's nothing to save.
Unit tests for content repository paged queries; amends to fix ordering issues
Fixed issue with list view filter; further unit tests for list view paging
Removed debug line
Moved added method from PetaPoco file to an extension method
