This adds the ability to verify email addresses of a user, so we know they have access to the email address on their account.
Until a user has verified their email address, any teacher of a class they're in can reset their password for them via the Teacher Dashboard. When a user's email address is verified, a teacher may trigger a password recovery email to be sent to the student.
Verification links are valid forever, until the user changes the email address they have on file. They are created using a timestamp, with a sha256 of timestamp+salt+userID+email. Currently the hash value is rather long, could be shorter.
