How do we invoke the wxPython UI as a stand-alone process?

For the Tcl/Tk UI, G_gui() essentially does:

	fp = popen("$GRASS_WISH", "w");
	fprintf(fp, "source $env(GISBASE)/etc/gui.tcl\n");
	generate_tcl(fp);

We need an equivalent sequence for wxPython, e.g.:

	fp = popen("python", "w");
	fprintf(fp, /* WHAT GOES HERE ? */);
	generate_xml(fp);

[There isn't a generate_xml() function at present; it's called
G_usage_xml() and has stdout hardcoded, so that needs to be
re-factored.]
