Jonas Jenwald 6129be7b68 Change the PDFViewerApplication.open method to only accept objects
If this method was added today, I really can't imagine that we'd support anything *except* objects. Unfortunately we cannot just remove this now, since the code has existed since "forever", however we can deprecate this and limit it to only the GENERIC build.

Furthermore, we can avoid a redundant `PDFViewerApplication.setTitleUsingUrl` call in the Firefox PDF Viewer since the title has already been set previously in that case.
