Title: Story - Driver Invalidation

1. Drivers now invalidate (i.e., is\_valid reports False and \_exec\_state reports "INVALID") whenever a parameter, objective, or constraint is added, removed, or cleared.

2.Removed the "Scope" editbox from the Constraint and Objective component editor boxes in the GUI.
