Build a new attack pattern chooser control

[infosec-alchemist]

We need a new control ( or group of related controls) for selecting an attack pattern. The following features are required to be implemented

• [ ] Allow grouping the selections by attack tactic. This is almost like a filter on top of tactics on top of the techniques.
• [ ] Allow text searching/filtering in the control. This could be across all techniques or just in the filtered tactic
• [ ] Incorporate the larger heatmap selector.
• [ ] Simliar control for use in filtering, or for selecting attack patterns to assign as part of an object relationship
