Getting the demo to work

- Deleted files 'example/www/js/ShowKit.js' and 'example/www/phonegap.js'. These files are not necessary because Cordova will add them when you build/prepare the project
- Adjusted all HTML files and changed 'phonegap.js' to 'cordova.js'. Also changed 'js/ShowKit.js' to 'ShowKit.js'
- Adjusted dashboard.html and changed input username type to text.
