	* thunarx/thunarx-menu-provider.{c,h}, thunarx/thunarx.symbols: Add a
	  new method get_dnd_actions() to the ThunarxMenuProvider, which allows
	  menu providers to install additional actions into the Drag'n'Drop
	  menu of the file manager.
	* docs/reference/thunarx/: Update the thunarx reference manual.
	* thunar/thunar-dnd.{c,h}, thunar/thunar-location-button.c,
	  thunar/thunar-shortcuts-view.c, thunar/thunar-standard-view.c,
	  thunar/thunar-tree-view.c: Insert the additional actions supplied
	  by the installed menu providers into the Drag'n'Drop menu.

+/**
+ * thunarx_menu_provider_get_dnd_actions:
+ * @provider : a #ThunarxMenuProvider.
+ * @window   : the #GtkWindow within which the actions will be used.
+ * @folder   : the folder into which the @files are being dropped
+ * @files    : the list of #ThunarxFileInfo<!---->s for the files that are 
+ *             being dropped to @folder in @window.
+ *
+ * Returns the list of #GtkAction<!---->s that @provider has to offer for
+ * dropping the @files into the @folder. For example, the thunar-archive-plugin
+ * provides <guilabel>Extract Here</guilabel> actions when dropping archive
+ * files into a folder that is writable by the user.
+ *
+ * As a special note, this method automatically takes a reference on the
+ * @provider for every #GtkAction object returned from the real implementation
+ * of this method in @provider. This is to make sure that the extension stays
+ * in memory for atleast the time that the actions are used. If the extension
+ * wants to stay in memory for a longer time, it'll need to take care of this
+ * itself (e.g. by taking an additional reference on the @provider itself,
+ * that's released at a later time).
+ *
+ * The caller is responsible to free the returned list of actions using
+ * something like this when no longer needed:
+ * <informalexample><programlisting>
+ * g_list_foreach (list, (GFunc) g_object_unref, NULL);
+ * g_list_free (list);
+ * </programlisting></informalexample>
+ *
+ * Return value: the list of #GtkAction<!---->s that @provider has to offer
+ *               for dropping @files to @folder.
+ *
+ * Since: 0.4.1
