Refactor Cite extension JavaScript and make it pass Jshint

Moved the scripts and the CSS into the modules folder directly
(like almost all other extensions do), added a .jshintrc to not have
jenkins shout at this change and minor stuff.

After this change Cite will no longer work with anything older than
PHP 5.3!
