* Important - Updated Scenarios to allow creating Conditions based on whether an option has been selected in a Component.
* Important - Scenario Conditions are no longer matched partially when configuring a Composite without having made a selection in every Component. Previously, a Scenario that hides Component n based on a selection in Component i (i<n) would always match while Component i was empty.
