Title: form_button() doesn't create a bootstrap button unless a class is specified

When you call form_button() without a class explicitly provided, it will not add the base 'btn' class, producing an unstyled html button. This means that there's not a nice way to create a default-style bootstrap button.

I just modified it to always add the btn class, even if a class is not provided with the function arguments.
