"Buffer is not defined" when calling schema.messageBox.messages

[macrozone]

simple schema version 0.3.1, meteor 1.5

this throws a "Buffer is not defined" error on the client:

schema.messageBox.messages({
    en: {
      required: 'This field is required',
    },
  });

this should have been fixed in 0.3.1: #134 but its not.

OK, yeah, looks like message-box package still uses deep-extend. Will need to do the same change there and update the dependency version in SS.
