Title: attendee newsletter CSV export

creates a CSV file that is ready to import into MadMimi (and probably other providers) of attendees who want to sign up for the newsletter

at some future point I will also do this with staff newsletter people as well.

need Eli's eyes on this before merge, appears to work correctly on my machine.
