Subject: 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.
