Added max_redirects and check_ssl_certs options
Made the Request's reference to WWW::Curl::Simple be weak, so we don't have a circularity and leak memory
Removed needless duplication of setting some curl options
added author testcase for check_ssl_certs option
Ensure HTTP::Response parses the last header, as we'll see multiple headers on a redirect
added testcase for max_redirects option
Merge pull request #7 from neilbowers/master
