Survey results do not include surveying node

[bboston7]

The current survey implementation forbids surveying itself. This was fine with the V1 survey because it was possible to get much of the same data via other means, but with the V2 survey it would be nice to get data from the same time slice as the rest of the nodes in the survey.

To accomplish this we would want to special-case these requests to be serviced directly rather than broadcasting these messages.
