Add support for onAfterEmailVerified hook

[infomiho]

We are missing one hook in the email auth lifecycle:

1. User registers
   2. (Account is not fully created - the email is unverified)
2. They receive on email
3. They verify their email by clicking on a link
   5. (Account is fully created)

We have hooks before and after the first point (user registers) but the account is not fully created at that point. We should enable our users to execute code when the account is fully created which makes more sense.
