As Patrick, I want to use epics for swimlanes so I can see progress of each epic within a sprint more easily.
- Both stories and subtasks for the epics should display.
- Only an option for Scrum boards
- The swimlane presentation is similar to "story task" swimlane: Epic Name, possibly issue key
- No detail view shown for epic; clicking on swimlane selects first issue in swimlane (same as Assignee)
- Issues without epics shows at the bottom
