Make the shortcut bar not alter the model by itself on a drag and drop
operation; instead, just emit some newly created dnd signals. The code using the library will then dispatch this to the appropriate data structures. Also, disconnect the model signals on ::destroy. svn path=/trunk/; revision=5574

+ * e-shortcut-bar.c (e_shortcut_bar_destroy): Call
+ `e_shortcut_bar_disconnect_model()'.
+ (e_shortcut_bar_on_drag_data_received): Don't add the item to the
+ model here; the view is only supposed to act as a view. Rather,
+ emit the "dropped_shortcut" signal appropriately.
+ (e_shortcut_bar_on_drag_data_delete): Likewise, don't remove the
+ item from the model and emit "shortcut_dragged".
+ (e_shortcut_bar_class_init): Install the "shortcut_dropped" and
+ "shortcut_dragged" signals.
+
+ * e-shortcut-bar.h: New signals "shortcut_dropped",
+ "shortcut_dragged". "selected_item" changed to "item_selected".
