feature request: include optional html_message in send_mass_mail tuple

[Michael Scheper]

It seems I'm not the only one who wants to include HTML in messages sent via send_mass_mail(). It also seems an easy feature to add; if the tuple has a fifth element, assume it's an html_message.

Actually, I feel like I'm reinventing the wheel by passing it though django.template.loader.render_to_string(), too. I've copied the same six-line function to numerous projects already.

I'm suggesting these features here, as per Requesting features in the docs.

Thanks!

Hi Michael, it looks like we're not enhancing send_mass_mail() as per the docstring [0]: "The API for this method is frozen. New code wanting to extend the functionality should use the EmailMessage class directly." Perhaps the documentation could be clarified.
