Add support for solving redirect loops (paywalls, etc.) by checking whether URL #1 is contained in URL #2; if so, assume that URL #1 is the one we want; e.g.:

* #1: http://www.nytimes.com/2014/05/04/us/politics/obama-white-house-correspondents-dinner.html?partner=rss&emc=rss
* #2: http://www.nytimes.com/glogin?URI=http%3A%2F%2Fwww.nytimes.com%2F2014%2F05%2F04%2Fus%2Fpolitics%2Fobama-white-house-correspondents-dinner.html%3Fpartner%3Drss%26emc%3Drss%26_r%3D0
Remove NYTimes test because it depends on a live URL
