Title: Attributes whitelisting based on the form's specified attributes.

Add an instance of the `AttributeWhitelist` class in `ActiveForm::Base`. This class will filter submitted params and will determine for each attribute if it should be assigned in the underlying model. If any attribute is not specified through the `attributes` directive, there will be no attempt to assign it.
