gui: Introduce visibleOnBlur config option

You can now prevent the tray window to auto-hide on blur by adding
the following to your ~/.cozy-desktop/config.json:

    "gui": {
      "visibleOnBlur": true
    }

It makes the app easier to use at least on i3wm (although it may also help
with other tiling window managers).

To actually hide the window, you have to either click on the tray icon or
use whatever other way your window manager is providing.
