Enhance redirect handling

[danmactough]

Enhance redirect handling: (1) response._redirectsFollowed reports the total number of redirects followed instead of being reset to 0; (2) add response.redirects, an array of the response.statusCode and response.headers.location for each redirect.

looks good, I'm on planes for the next few days so it might take me a bit to get it merged.
