Update: Improve Socket Definitions and UI for Deformers

 - adds Viewport/Render toggles
 - fixes Smooth Deform somewhat
 - UI for Smooth Deform to show/hide Scale parameter
 - new Inverted Boolean to simplify UI of Smooth deformer

still to do: add viewport/render toggles to other deformers
add "Length-weighted" smoothing option to smooth deformer
