Title: Addressing Issue #1973

I'm not sure how to submit a PR that's somehow connected to [another person's issue](https://github.com/twitter/bootstrap/issues/1973)... sorry about that. (if that's even possible)

Basically, within the `toggle` method, I added a check for the class `.disabled` or the attribute `disabled`.
