I have updated todoApp for the view config change, and to use a has test for the emoji data for ios

dojox/app changed the way the config is done for the view, it had been required to set "controller": "none" if you did not want a controller, and it would default to try to find the controller if you did not specify one, now if you do not want a controller you will not set it, and you will have to set it if you have a controller for the view.  I have updated todoApp for this, and I changed todoApp to use a has test for the emoji data for ios.
