Because jQUI's build process no longer provides individual minified files we need some additional changes:
* Rename all files, remove the "jquery.ui." prefix. Add old files to `$_old_files`.
* Add and use non-minified files in /src.
* Add grunt task to minify jQuery UI files.
* (Non-minified files will not be shipped.)

Changelogs:
* http://jqueryui.com/changelog/1.11.0/
* http://jqueryui.com/changelog/1.11.1/
