Modify getBootstrappedData to check properties for more models and collections

[saponifi3d]

Running into an issue where a model which contains nested models doesn't correctly get passed from the server to the client.

This PR makes it so we can use the parse function to build out models and then still have bootstrapData hydrate the view.

usage:

// ... in some model ...
parse: function (data) {
  if (_.isObject(data.subModel)) {
   data.subModel = this.app.modelUtils.getModel('SubModel', data.subModel, { app: this.app });
  }
  return data;
}

Then this subModel will be added to the bootstrapData correctly, putting both the Model and SubModel into modelStore in the hydration step... making view "subModelView" model=subModel work in the template to correctly get the data for a subview.

This is a fix for: #263
