naneos.gui.app

The naneos-gui command: a tray icon that runs the device manager.

naneos-gui                       start the tray app (a second start does nothing)
naneos-gui --quit                ask the running one to stop and wait for it
naneos-gui --autostart on|off|status
naneos-gui --integration install|remove   app bundle / application menu entry
naneos-gui --version

Everything but the tray app itself works without Qt, so the installers can use it right after installing and a missing naneos-devices[gui] gets a clear hint.
