Formtastic by default

Why there is formtastic class by default? It's not good. Maybe, there is a place for another css class, like contact-us?

Formtastic used to be the default, but class must not have been removed after adding https://github.com/JDutil/contact_us/blob/master/app/views/contact_us/contacts/new_formtastic.html.erb template. You can submit a PR to remove it if you want, but it doesn't seem to bother anyone else.

I plan to do some refactoring for this gem. I'll try to do this.
