Accounts - Email not found [315]

We handle emails differently in just about every place that uses them. This causes issues when someone registers with EMAIL@EXAMPLE.COM but we modify it to be EMAIL@example.com as that portion was case-sensitive and the user didn't know their email address was modified.

This goes through all of the places that deal with retrieving or storing email and makes them case-insensitive.

All tests pass. I think I caught all instances that matter.
