* lib/net/http.rb: adding support to rfc5789 patch verb.

  Added a Net::HTTP::Patch class which expects a message body
  and response body. It recycles the post method into a patch one,
  that will send the encoded representation to the server.
  Summarizing, a new class has been created, the post method
  extracted into send_entity, including a new argument,
  which defines which class to use (Post or Patch) and
  finally a patch method was created. [ruby-core:30426]
