Not all SlideShare URLs generate preview

The URL `http://www.slideshare.net/nicolaasmatthijs/apereo-oae-state-of-the-project` generates a preview as expected. However, `http://www.slideshare.net/nicolaasmatthijs/apereo-oae-state-of-the-project?from_search=3` does not generate a preview.

Unfortunately, all SlideShare presentations that you get to from the search interface now have the `from_search` parameter.
