[PATCH] setenv "DISPLAY" when activation extension menu item

[Christian Neumair <chris gnome-de org>]

The attached (totally untested) patch calls g_setenv before activating
an extension action, proxying the current FMDirectoryView's screen to
the environment of a spawning child process (NB: gtk_widget_get_screen
returns the default screen if the widget doesn't have a current screen).
Users complained that nautilus-open-terminal doesn't open on terminals
the correct display.

It also adds/removes a ref to the FMDirectoryView providing the
extension actions.
