Fixes #617, #2271 User validation removed from core to UserValidationByEmail plugin. Without a validation plugin, users can login immediately.

Fixes #2243 Removed "You have validated your email" email. Users are logged in immediately after registration or validating email.
Refs #2409 Added register, user plugin hook that is called only on self registration. Can be used to halt registration.
