Pairwise 0.2.0

• Pairwise needs only Accessibility now. While dragging you see an empty plane with each window's icon and title, and nothing is recorded.
• Still or live pictures while dragging, new settings that take Screen Recording. Live keeps video playing and the seam sharp, with macOS's purple recording icon.
• Settings comes to the front when you open it from the menu, also from another desktop.
