Add real-time visualization of peers

[benhylau]

On the Me page, we want to show a node graph to represent the all the direct connections to your phone. It gives an idea of how well-connect you are to the mesh network at the moment. Some relevant information may include:

• Last four bytes of your peer's address as in fc00.org
• The peering protocol expressed in colour code (e.g. IPTunnel, BT)

I am thinking a WebView loading a local JS implementation like this will do. See discussion on this topic here #16.

@benhylau, do you have something to get nodes' graph in the app?

Not the UI, but I think you can get the data with this:
