v0.6.3

Fixed

• Bridge listener no longer dies with NameError: name 'socket' is not defined after renpy.reload_script(). The listener thread survives a
  script reload, but the reload wipes the Ren'Py store — the __globals__
  of init python: functions — so the bare except socket.timeout: in the
  accept loop raised NameError on the next 0.5s timeout and silently
  killed the thread. The game kept running with a dead bridge until the
  process was eventually closed. The listener and its helpers now use
  function-local imports (read from sys.modules, which reload never
  touches), and the accept loop also tolerates non-timeout OSError.
