Ian Paschal 2304aeaceb Expanded states preserved when updating models
Did this so that models can be updated more often fixing bugs where when a material is set as "not favorite" in the favorites section, its updated accordingly in its "normal" section.

It's also the ground work for saving material section expansion to preferences.
