    keybindings: Stop keybinding if a touch happens while Super is pressed
    
    We use the combination of pressing Super and clicking+moving the mouse
    to drag windows around and we also support pressing Super and using the
    touchscreen to drag windows.
    
    Since we don't want to show the overview when the Super key was used to
    initiate a window drag, prevent showing the overview in case a
    TOUCH_BEGIN or TOUCH_END event happened during the key was pressed.
