* ext/psych/emitter.c (initialize): allow a configuration object to be

  passed to the constructor so that mutation isn't required after
  instantiation.

* ext/psych/lib/psych/handler.rb: add configuration object

* ext/psych/lib/psych/visitors/emitter.rb: use configuration object if
  extra configuration is present.
