Changes for version 0.15
- fixed a bug when using arrays in the "response_body" (and other similar) section when there was only one request.
- fixed presentation problems in the HTML generated from the POD.
- added documentation for the TEST_NGINX_* variables.
- added "local $?" in Test::Nginx::Util::END to avoid confusing Test::Builder::_ending()
- removed "use Test::More" from Test::Nginx::Socket because Test::Base already loads it.
- Test::Nginx::Util in lib/Test/Nginx/Util.pm
