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.

The Vellum Solver DOP and SOP now have a global Velocity Damping parameter similar to the one on Vellum Drape, which applies an overall damping to Vellum particles' velocity.
