nautilus/nautilus-bnc363122-lockdown-context-menus.diff

https://bugzilla.novell.com/show_bug.cgi?id=363122

Add a way to disable context menus in Nautilus's file views, for
quick-and-dirty kiosks.

This adds an /apps/nautilus/lockdown/disable_context_menus GConf key;
if set to true, it will disable all the contextual menus on file views.
