Use require.js to ensure that JS files are executed only after loading completes

[Davis Marques]

Intermittent page update problems could be suggesting that the Javascript files are not loading in order and that is causing problems for Angular. Use require.js or a similar approach to guarantee that resource loading completes before any script execution happens.

Have added app-compact.sh and app-minify.sh scripts. These scripts compile the separate Angular script files into app.js, controllers.js, directives.js, filters.js and services.js. The minify script reduces the file size.

Have moved all Angular application script directives to the bottom of the HTML page. The core script libraries (ex. JQuery, Bootstrap, Angular) are declared in the page head.

Used Angular's async loader instead of require.js to ensure execution starts only after all files are loaded.
