[Rd] patch to add a menu item in Rgui for RSiteSearch

[Liaw, Andy]

Please consider adding the following to the next R release (I understand
that it's too late for R-2.1.0).  It adds the menu item `Search R Site' in
the `Help' menu in Rgui (which calls RSiteSearch() on the input string).

Best,
Andy
