Describe the bug
Material List does not save your preferred sort order

To Reproduce
Load any blueprint or copy from an existing area in your world. Open up the Settings Menu ('G' by default I believe) and chose the button to view the Material List to see what materials would be needed to paste the copied structure into the world. As soon as you close the material list your choice is lost and you have to cycle through the preferred sort order again to find the one you want

Expected behavior
Sort order on the material list should default to the last one used
