Materials Utils: Update to Mix Nodes, report switch

Changes mostly touching materials_cycles_converter
Add color mix nodes tree between images and shader input
Add a scene prop for switching off the report in the UI
Remove the preferences conv_path entry it's not used
Remove the Value to RGB node for now (adding it properly needs an
refactor)
Change the placement of the texture nodes (hidden if > 1)
