Parameters of copied objects remain paired without indication

[JansenSmith]

Parameters are added in the add step and duplicated in the copy step.

regeneration lambda is in the add script context and that context would need to be recreated somehow....

two options:

• recreate the add script context to remove parameters being shared
  OR
• in UI, make it clear which objects share parameters

maybe have parameters continue to be shared with Duplicate? it'd be nice to OPTIONALLY have shared parameters, as long as the sharedness is overt in the UI
