- setting up our scripts for an AJAX call

Now we have our JS enqueue in WordPress properly.

Our second function piggybacks on WP localization functions so that we
can call the proper AJAX location in WordPress. ALWAYS call WordPress
admin-ajax.php for an ajax request.

Finally we have a basic JS start in WordPress. Other JS libraries
(Prototype) use the $ as well so this start tells us that every script
inside using the $ is calling jQuery.
