Reference to old "pdfDirectory" in the code

[oscargus]

In UrlDragDrop there is the following piece of code:

                        //auto filename:
                        File file = new File(new File(Globals.prefs.get("pdfDirectory")),
                                editor.getEntry().getCiteKey() + ".pdf");
                        frame.output(Localization.lang("Downloading..."));

This should be changed to use, if nothing else, the correct directory and preferably the correct file name.

UrlDragDrop .java is never used in current master?! Only SimpleUrlDragDrop.java.

See #1454, #121

Also, the FieldProperties.URL seems to be never used at the moment.

        } else if (fieldExtras.contains(FieldProperties.URL)) {
            return FieldExtraComponents.getURLExtraComponent(editor, getStoreFieldAction());
