Remove letters-related code (#175)

This deletes a big ol' chunk of code related to letters. It's not everything—there are still a few things that might be tied to sms/email—but it's the the heart of letters function. SMS and email function should be untouched by this. Areas affected: - Things obviously about letters - PDF tasks, used for precompiling letters - Virus scanning, used for those PDFs - FTP, used to send letters to the printer - Postage stuff
