Subject: * 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]   Patched by Guilherme Silveira
