drey 0.1.8

Fixed

• serve now gives up on a client that never writes anything, instead of
  parking on stdin forever. The daemon side already bounded the reverse
  handshake (0.1.5's INIT_TIMEOUT: a backend that doesn't answer
  initialize within 60 seconds is given up on), but nothing bounded a
  client that opens the shim's stdin and never sends its own initialize.
  That left an orphaned drey serve process per abandoned attempt, sitting
  outside drey status (which lists backends, not shims) and outside process
  accounting until something went looking. A client that writes nothing
  within 60 seconds now gets the same treatment: the shim exits instead of
  hanging.
