Hi, thank you for creating such a great plug-in, I love it.

I have added proxy environment support to your plug-in, so that recaptcha works when you're behind a proxy. Here are the relevant lines:

lib/recaptcha.rb line 56

    begin
      proxyargs = []
      if (proxy = ENV['http_proxy']) then
        uri = URI.parse(proxy)
        proxyargs << uri.host << uri.port
        proxyargs << uri.userinfo.split(/:/) if uri.userinfo
      end
      recaptcha = Net::HTTP::Proxy(*proxyargs).post_form URI.
        parse("http://#{RECAPTCHA_VERIFY_SERVER}/verify"), {
        :privatekey => private_key,

Thanks again

James
