Allow hiding of statuses from Kanban views

In both the Feature Workflow board and the Ideas Board, teams that use a shared Status workflow may not all utilize every status. During some key planning exercises, not all statuses may be required or pertinent.

Lost screen space/real estate. Users migrate to cleaner views and export/re-import or avoid the view altogether.

Allow for the complete hiding (Feature Workflow has this but only minimizing) of statuses - driven by the Statuses selected in the filter.
