Fixes #118. I made it such that emails are only considered duplicates if they want to make a user account of the same type. This hopefully addresses the concern of a student using a parent email and the parent also wanting a guardian account using the same email. I also removed the first and last names from being displayed, since that feels like a bit of a privacy issue. I also changed the default tag setting to check for duplicate emails.
