Title: add gravity, distance and charge parameter to D3forcegraph template

I had some problems to visualize a big, densely linked graph due to the fixed gravity, distance and charge parameter in the D3forcegraph visualization template.
This small change allows you to modify the parameters in the template:
```
{{models.main|D3ForceGraph:"sourceNode,targetNode,charge=-20,gravity=0.001,distance=300"}}
```
