What changed in 0.2.51

• The app no longer freezes when a device connection drops. Port forwarding, the ports panel, and session refresh now run their SSH work off the UI thread and time the connection out quickly, so an unreachable device shows as unavailable and resumes on its own once it reconnects, instead of hanging the whole window.
• Closing a window tile now always terminates the exact window it maps to. The managed terminal server no longer renumbers windows out from under the grid, so a terminate can no longer miss or close the wrong window.
