Add support for Dojo Mobile CodeGlass live examples: when the 'theme' param. of code-example is "deviceTheme", it imports dojox/mobile/deviceTheme.js using <script> instead of importing dijit's claro.css, and adds the hidden visibility style on <body> instead of setting the claro class.  Secondarily, improvements of the formatting/indentation of the generated source code.
