Can we get real "close/minimize to tray" action?

Right now (1.3) there isn't any way to get onionshare out of the window list bar. Even when minimized, it still takes up that space.

Can we do a minimize or close to tray? There may be times when onionshare is running for hours at a time, and it would be nice if the gui could stay out of the way in those cases.

The cli version also employs a window which cannot be gotten out of the way; cli isn't an alternative.

Tray notifications are nice, but I feel like the main reason tray presence is a thing is to conserve real estate and reduce clutter.
