General Filter: Hide Added Concepts & Add Filter option to Include Added Concepts

As an end user of the OCL client, when I am in the Import existing concepts --> Pick concepts workflow, I may want to be able to see which concepts I have already added to my dictionary.

However, more often, I do not want to see the concepts I have already added from my dictionary, because I start to get confused about what I have vs haven't already added.

Task: Implement a Include Added Concepts option in the filter menu the user sees when they are in the Import existing concepts --> Pick concepts workflow. As part of this ticket, concepts already added from the dictionary/source should be hidden/excluded by default.

The wireframe below shows how this filter would be at the bottom of the filter options list, because this is not a common filter.

Acceptance Criteria:

As an end user, I should be able to see the filter option for Include Added Concepts from concept lists in the following views:

• When reviewing options in the Pick concepts list (get there by clicking Import existing concepts --> Pick concepts)
• I should not see already-Added Concepts by default.
