API to store test runs

[wickett]

At the end of a gauntlt run, the server should accept the run output and store it. We should be able to query it later.

Gauntlt may need to be changed to make this happen and something added to the gauntlt support files to handle this, but something like this should work.

$ gauntlt --with-server example.com

In the above code it assumes example.com is the gauntlt server. Also we might think of enabling this at the end of each scenario or other steps we could call. Maybe add these steps to gauntlt.

Given the gauntlt-server is running at example.com
Then send the output to my gauntlt-server

Sound good?
