JQuery Animations

This pull request makes numerous use the default jQuery animations when showing and hiding objects. It also adds a new initialization option to numerous: animation-options, which allows users to pass a different set of options to jQuery's show and hide functions: http://api.jquery.com/show/ (durration, easing, complete, step, queue, and specialEasing are all supported).

Note that I used Google Closure to generate the new minified js file.
