DOP IO and DOP Import Fields will properly compress fields after the first one.

Connecting Constant VOP inside Material LOPs not only sets the shader attribute value, but also disconnects any USD shader inputs. This is useful in Edit Material LOP to disconnects shader inputs defined in other layers.

Changed all Edit Properties-based LOPs (light, cube, camera, etc) to replace the "Create Primitives" check box with an "Action" emnu that can be set to "Create" or "Edit". Existing hip files should still load properly, as the underlying parameter name was not changed, just the UI.

SOP Merge Field dynamics operator now searches the input SOP's geometry for all occurences of the given name and merges each in turn. This change also similarly affects the Volume Source DOP.

Add volume visualizer buttons to the SOP Pyro Solver to quickly visualize common fields.
