Allow a swimlane in the Kanban, Scrum and Agile board to be associated with multiple statuses

[#1]

It would be helpful to allow an admin to assign several statuses to a single swimlane. If we have 7 statuses that we use, combining something like "On hold" and "Pending Approval" into a single swimlane (but differentiating colors for each status) would save room on the board layout making it easier to navigate. Thanks!
