Build arrow indicators into tutorial array

[gricha2380]

There is now an object for tips and a different object for tutorials. In tutorial array, create object containing arrow position and arrow type.

e.g.:

tutorial:[
    {
      "tip":"You can do things",
      "arrow": 
        {
          "direction":"down",
          "position-x":"50",
          "position-y":"50"
        }
    }
]
