RequireJS lazy-loading

Instead of loading all modules on page load (within the main bootstrap script) you can use require('string-module') within a module to lazy-load more modules.

The build script will still be able to pick up these other modules - but remember that although 'during development' you may be lazy loading the scripts, the build script is creating a single file with all your modules included so you aren't *really* lazy-loading once you deploy via the build script UNLESS you specify the modules that you want to be lazy-loaded as 'excluded' (see app.build.js for an example).
