Auto launch to tray

It would be great if auto launch option, instead of showing the window, automatically closed Salad to tray. It really bothers me to see the Salad window every time I log in on Windows.

This would be a great addition, but might make some people worry about Salad silently opening to tray (Yes it could be an option that is disabled by default, but people would still check that box and then complain about it starting silently).
