Refactor to 'gui/toolkit/'

    * add a example cmds/consolemouse
       uses a console button to launch the andlabs/ui
    * fix wrong return value in toolkit/NewLabel()
    * redirect STDIN output to a file
    * wonderful fix of Window() exit
    * finally remove the ancient stupid variables x & y
    * phase out struct 'box' and use 'node' instead
    * better names for things: use NewFoo() and NewBar()
