"Apply to selection" for physical materials and appearances

[Ron_Young]

Add an "Apply to Selection" function in the appearance and physical pallettes node menu to allow quickly swapping assigned nodes, without the need to visually drag to bodies potentially hidden or buried deep in multiple nested groups (I.E tedious and error-prone busywork)

This would allow changing those attributes on a large number of components at once to become the trivial effort by doing

"select object applied to" followed by selecting the replacement and using it's "Apply to Selection"

I.E. Similar to the node assignment UI functionality in Maya.
