	* app/widgets/gimpcontainergridview.[ch]: added a "selected_item"
	pointer to the GimpContainerGridView struct so we don't need to
	remember it using g_object_[set|get]_data(). Also make sure that
	the selected item doesn't get out of sight when resizing the view
	and that it is always visible initially.

* app/plug-in/plug-ins.c (plug_ins_init): make sure all progress
bars and at 1.0. Build the list of extension procedures to start
bars end at 1.0. Build the list of extension procedures to start
before starting them (and don't start them while iterating the
list of procedures because the list changes if we start an
extension).
