Hand Mirror 1.1.13

Repoint Ctrl+Shift+R to check for a new app version

Ctrl+Shift+R now checks for (and installs) a new release like a browser
hard-refresh, instead of refreshing the camera. The window raises an
UpdateCheckRequested callback that the tray handles with balloon feedback
("You're up to date" / "Update available"). Camera refresh stays available
via the tray "Refresh camera" item (and is still used on camera switch).
