Changes in 2.1.3

• Features
  • Proxy Authentication for SSL.
  • Performance improvements.
  • Full RDoc. Please tell me any English problem. Thanks in advance.
  • Do multipart file upload when a given body includes a File. You don't need to set 'Content-Type' and boundary String any more.
  • Added propfind and proppatch methods.

• Changes
  • Avoid unnecessary memory consuming for get_content/post_content with block. get_content returns nil when you call it with a block.
  • post_content with IO did not work when redirect/auth cycle is required. (CAUTION: post_content now correctly follows redirection and posts the given content)
  • Exception handling cleanups.
    • Raises HTTPClient::ConfigurationError? for environment problem (trying to do SSL without openssl installed for example)
    • Raises HTTPClient::BadResponse? for HTTP response problem. you can get the response HTTPMessage returned via $!.res.
    • Raises SocketError? for connection problem (as same as before).

• Bug fixes
  • Avoid unnecessary negotiation cycle for Negotiate(NTLM) authentication. Thanks Rishav for great support for debugging Negotiate authentication.
  • get_content/post_content with block yielded unexpected message body during redirect/auth cycle.
  • Relative URI redirection should be allowed from 2.1.2 but it did not work... fixed.
  • Avoid unnecessary timeout waiting when no message body returned such as '204 No Content' for DAV.
  • Avoid blocking on socket closing when the socket is already closed by foreign host and the client runs under MT-condition.
