Addons: Material Utils - Revised code, added descriptions, fixed error if material slot is empty, made Material Replace operator a popup and added feature to update selection based on affected objects. As the dropdown of prop_search may reach over the borders of the popup, 2.66.6 is required, as the entire popup was closing before this version (now the click is only handled by the dropdown list, see bug #35154).
