this module implements a tray icon for Labyrinth.

As of now it only brings the application to front if it is clicked.

      Its a tray icon that you can parameterize during initialisation with the name or file of an icon, with a menu and a simple callback

      It will create such an Icon, will display the image, call back the callback when left clicked and pop up the menu
      when right clicked.
