Issue49 Query Results Post Processing

[SamHard]

This handles the breaking changes referenced in evo-terren#49 by doing the processing that used to be done in Gremlin.Net after the fact. It's not pretty, but it allows us to keep more up-to-date with the Gremlin.Net library.

The more I think about it, the more I think this is the wrong direction. The main thing is that this hack won't work if the GraphClient constructor accepting an IGremlinClient is used, and there is a pull request (PR 56) proposing to make that constructor public. We'd be better off rolling back to an older version of Gremlin.Net, as proposed in pull request 51, until we can fix Gremlin.Net.
