local property should override preset property

[mvanbrab]

As an example in a node, the resulting fill color should be green, regardless of any fill color defined in the preset:

   {
        "id": "thing1",
        "label": "thing 1",
        "preset": "coloredThings",
        "fill": "green"
  }

This is fixed by issue #132

{
    "graph": {},
    "node": {
        "presets": {
            "preset1": {
                "shape": "8-star",
                "fill": "yellow"
            }
        }
    },
    "edge": {}
}

[
    {
        "preset": ["preset1"],
        "fill": "red"
    }
]

Result:

---

So the local fill has priority on the fill of the preset.
