APPWTV-39 Fixed production build

**APPWTV-39**  
fixed problems with production build by correctly setting the sections in app.json.   Also moved Ui.js in .sencha/app/sencha.cfg to be built correctly.  

Download & install [Sencha Cmd](http://www.sencha.com/products/sencha-cmd/download)  
Open a terminal and type:  
```bash
sencha app build production  
```
