For any process, the __main__ module (the one which is executed rather
than "import"ed) should call gettext.install. This inserts the "_"
function into the global namespace.

The call in wxgui.py should be sufficient for the GUI itself, but
menuform.py also requires it for the case where it is executed from
G_gui().

IOW, any module which uses:

	if __name__ == '__main__':
	    ....

(other than for debug/test/demonstration purposes) should call
gettext.install within that section of code (calling it from the top
level is suboptimal, but probably harmless).
