Adding Email Service

Hey Will,

I added this email capability because I didn't want to have to use the paid texting thing. I didn't do any fancy formatting on the email, I'm sure you could do that better than me. But the commands changed a bit to support both text and email services. I removed the config.py file from the repo because I didn't know how to encrypt it, but clearly the app still uses it. Let me know what you think; I can keep working on this PR or you could edit it or you could just dump it, no hurt feelings. Let me know.
