Add tabs delete method including event namespace to protect non-jQuery Tools events.

I'm sure nobody cares about this project any more. I've always been a fan of jQuery Tools Tabs because it's easy to get up and running with custom layouts.

I've added a delete method which comes in handy especially for responsive design sites.

I assume your repo is out of sync with the official build (v 1.2.3). 1.2.3 has a destroy method but I didn't find it to be complete enough and couldn't dig up a non-minified version off their site. Maybe I'm blind.

Oh well, maybe someone will find this useful someday.
