Fallback email sender

As before, I think this is best handled by a backend that implements the "fallback strategy". So you have:

• django_mailer, which provides a mail backend that saves things to the DB for later sending
  • and requires a single other backend to actually do the sending
• a "fallback strategy" backend that is either hardcoded to use 2 different backends, or could be configured to use a list of other backends.
• you then point MAILER_EMAIL_BACKEND at your "fallback strategy" backend

Structured this way, you can compose the behaviours you want very nicely, without having to tie any of these together. So, for example, your "fallback strategy" backend could be used without django-mailer at all.

If there is some reason this won't work, please let me know.
