first pass at generating specs

This is my first pass at generating the specs; I'm just parsing the HTML from the docs into JSON that somewhat resembles the example buttons.json file.  

Because the docs don't detail everything, these are going to have to be fixed by hand, but I'm aiming for a good starting point.  

Any suggestions would be very helpful.

Oh, and here's an [example](http://jsfiddle.net/PccjJ/1/) of using the JSON to do cool stuff.  In this case it's a form generated from the JSON data; that allows you to change properties of the button (add/remove classes).

Eventually, I'll write parsers for the collections/modules.  I also want to make a page where every possible combination of styles is show, which will help us track down bugs without waiting for someone to complain :-)
