Remove the port files and references to it from the common headers and elsewhere. Also remove GPE (GNOME PDA Environment) support as libgpewidget is unmaintained since 2006 or so and has never been really used. Use __WXGTK__ to test for any version of wxGTK now. Still define __WXGTK20__ for compatibility, but always define it now and don't test for it in the library code.
