Fixed problem with missing menubar on GTK2.   Also switched to using GPOINTER_TO_INT() and GINT_TO_POINTER() to avoid compiler warnings on 64bit systems in *most* places.  There are still some more complicated warnings to go... maybe we need similar macros to avoid warnings on the other platforms as well.
