v0.1.15

PassTheStick v0.1.15 — Auto-update + silent installer upgrade

New: app checks GitHub on startup and shows a tray notification
when a newer version is available — click to open the download page.

Fixed: installer now upgrades over previous versions silently —
no more "uninstall first" required. Just run the new installer on
top of the old one.

Download PassTheStick-Setup-0.1.15.exe and run it.
