Added button to update current style #3293

Example - https://i.imgur.com/f4Yi3MR.png
Now changing style type should be a bit more intuitive - previously there were no button and it wasn't possible to change style type for all selected objects / changing style type for the entire scene were hidden in N-panel Miscellaneous section.

Now it also able to change style type for all blender materials, even the ones that don't have any objects using them (wasn't possible before 7c0c934b4)
