The javascript modules are compressed into one file using the requirejs-maven-plugin (https://github.com/bringking/requirejs-maven-plugin) - working on #4

It doesnlt work with jquery and jquery ui loaded from a CDN ( see http://requirejs.org/docs/api.html#config-shim), so they have been added to the js directory. jquery ui is optimized by removing all the unneeded features.
