Global configuration for overridable defaults

You can now override defaults and specify your own, by adding a flashMessageDefaults option to config/environment:

module.exports = function(environment) {
  var ENV = {
    // ...

    flashMessageDefaults: {
      timeout      : 10000,
      priority     : 200,
      sticky       : true,
      showProgress : true,
      type         : 'foobar',
      types        : [ 'warning', 'notice', 'foobar' ]
    },

    // ...
  }
}

This lets you override defaults for various options – most notably, you can specify exactly what types you need, which means in the above example, you can do Ember.get('flashes').{warning,notice,foobar}.

Thanks to @johnotander for this feature.
