send domain default digests to alternate email

[dmorton]

We need to either specify an address to send domain default digests to or send it to all admins for the domain. This involves a bit of difficulty since the digests make use of user id's and tokens; the support isn't quite there yet for this.

Possible considerations: I'd like to make it easier to link domain defaults to an admin so they can view items with their own caches or at least in a place easier to get to. This ticket may go well with that feature.

A possible solution that would work well for 1.0.3 is to send digests to all domain admins. Just special case the domain accounts and loop through the admins for the domain.

If two admins try to admin the same message, there may be some confusion, but I don't think it's that big of a deal.

First stab in [1315]

Need to either show all recipients in the envelope to in the digest, or at least filter that list for addresses in the domain being processed.

Also still need to add a parameter specifying which real user_id to use - and verify it in the login process that the user is still an admin for the domain. Then we could set the admin up to already be impersonating the domain.
