Also, made performance tests point to reporter helper method &passed in more information into concurrency test.

Continuing to implement "scenario" method so that it logs in, gets feed, logs out, captures details.
Merge branch 'performance' of https://github.com/sjdixon/spawncamping into performance
OK I think scenario works!
Fix check if user follows another user
OK I think scenario works!
Callbacks seem to work OK - appear to be returning the context after all the methods are called, but it doesn't look like the sessions are concurrent.
Scenario - I know that post works but the return value is not being blocked as I hoped.
Got login working, now working on feed.
Committing code that submits feed request without server hanging up, but then fails to login with the cookie for whatever reason.
Added some headers, in the hopes they should work.
The magical solution to cookies and all related problems in the needle request.  Also put a stub to Jeremy's clean code for doing requests.

Conflicts:
	test/general/helpers/scenario.js
Implemented scenario as a timeout function and fixed an issue with runset returning before promises were resolved.
Before Jeremys skeletoni
Completed scaffolding for scenario.
Scenario now has logout; still missing individual get requests for each of the images in the body of the html.
Added assertiont that the number of images returned is not 0.
Added assert and cheerio to package.json
Added code to systematically parse and verify that each image is loaded.  However, it doesnt work because the feed items are not generated fast enough.
This can be demonstrated by doing 'grunt | grep 'ASDASD' which will show you the current number of images returned by the query, and by the fact that
the number reported is different depending on whether you go in from the browser or from the performance test.
