Autofill Field Classification improvements.
* Changed the remoteId -> userValue API to userValue -> categoryId so the
category could map to multiple values (for example,
"email" -> "email1", "email2")
* Added method and settings for maximum number of category ids.
* Tuned the default value of some settings.
