sbutler - Enhancements 2

Much work done on the plugin. I'm developing on WP 3.5. WP 3.4 should (probably) work, but I'm not testing it. And anything below that I don't know.

* Reorganize the awards.php and badges.php classes
* Enable rich badge criteria and award evidence pages
* Check badge and award fields for validity
* Statistics on badges
* Categories for badges
* Split award JS into its own file
* Fixup the award JS to handle bad browsers and errors
* Use AJAX to notify WPBadger of award backpack acceptance/rejection
* Hopefully better filtering inside the JSON assertion
* WP 3.5 support
* Many bug fixes
