[PATCH] Don't setup clipboard handling twice for the same widget

[Christian Neumair <chris gnome-de org>]

Renaming a file while another rename is in progress causes breakage due
to twice setting up the same editing widget. The attached patch prevents
Nautilus from setting up clipboard handling for the same editing widget
twice.
We silently assume that the widget always stays in the same window. The
UI manager is not changed on reparenting.
