Version 1.1.6

o  all:  use 'attr_reader/writer' instead of 'attr'
o  http.rb:  get/head allow implicit 'start'
o  http.rb:  change connection state algorithm
o  http.rb:  process user header before write
o  protocol.rb:  refine start/finish
o  protocol.rb:  Command#last_reply
o  protocol.rb:  ReplyCode.error!
