Change the behaviour of AutoFetch so that it will NOT include Lobs that are FetchLazy.

By default Lob's are set to FetchLazy ... so by default AutoFetch is now not going to include them in the query (when it currently does).

This change is due to the high performance cost of fetching lots of Lobs. That is, fetching the Lob's later using lazy loading is generally going to be a more performant. If you wish to fetch the Lobs eagerly using AutoFetch then you need to mark them as FetchEager or use a manually tuned query.
