Title: Case-insensitive email search in emailIsTaken

Email searches were not case-insensitive; using "test@foo.com" and
"TEST@FOO.COM" let me sign up for two separate accounts.

This is technically a security flaw because a user can theoretically sign up for as many accounts as they have alphabetic characters in their email.
