Reinstall Safari Extension

[NickLowe]

A more idiot-proofed expansion of these instructions (which worked for me once I realised that of course I needed to relaunch Safari after launching the new copy of DT):

@BLUEFROG

1. Download a new installer.
2. Unzip it.
3. Double-click the .dmg to mount it.
4. Quit DEVONthink 4 and Safari.
5. Drag and drop the application to the /Applications alias in the window, overwriting the currently installed version.
6. Control-click the window and eject the disk image.
7. Launch DEVONthink 4.
8. Launch Safari.
9. Go to Safari’s Settings > Extensions and enable our browser extension.
