limit nokogiri to "< 1.6". fixes #468

nokogiri 1.6 dropped support for ruby 1.8.
updated the changelog [ci skip]
convert keys for qualified messages w/o namespace

possible fix for #461
added #xml and #to_s aliases to the response

these return the raw http response body.
use alias_method instead of alias
internal renaming of response#to_xml to #xml

does not affect the api, because both methods still exist.
fixed response#header and #body /cc #474

both methods now respect the global :convert_response_tags_to and
:strip_namespaces options and return the expected result instead of
raising a Savon::InvalidResponseError.
