Adding some fields to users table, and the emailVerifySession table

Adding a required field for email address, and boolean for whether or
not the account has been verified. Added logic to fill in those values
appropriately.
Yet more cleanup

Getting rid of more code that I used to figure out what I was going to
do with this all.
Adding empty files for later use.

Just what it says. Email.py is intended for email handling. EmailVerify
is intended both as the place to ask for the server to send an email
verify, and to receive the GET query to verify.
