Subject: [PATCH] window: Fix criticals when moving file to trash

The "gtk_revealer_get_transition_type: assertion 'GTK_IS_REVEALER (revealer)'
failed" critical is printed when moving file to trash after closing a window.
This is because the "undo-changed" signal handler is not disconnected when
the window is destroyed. Let's use g_signal_connect_object() to ensure
disconnection and prevent those criticals.
