Bootstrap-email

Small tweak to css to make `<a>` tags in buttons display block so when the outer button stretches and adjusts the inner contents will follow.

Returns the response from the `mail` method in rails so the `bootstrap_mail` method will perform the same as the `mail` method with inputs and outputs.

Thanks to daniellytle for the contribution on 148!
