Allow adding routes at runtime by using `App.MapRoutes` instead of `App.Router.map`

Ember-Runtime-Map.js

App.map_routes = [];

App.MapRoutes = function(routes) {
    App.map_routes.push(routes);
    return App.Router.map(function() {
      var route_lamda, _i, _len, _ref;
      _ref = App.map_routes;
      for (_i = 0, _len = _ref.length; _i < _len; _i++) {
        route_lamda = _ref[_i];
        route_lamda.call(this);
      }
      return true;
    });
};
