Title: Respect ActiveRecord::Base#new without_protection option

ActiveRecord::AttributeAssignment#assign_attributes – and thus by extension ActiveRecord::Base#initialize – support passing of a second hash alongside the attributes. If that hash contains :without_protection => true, the attributes are not sanitized.

IMO, default_value_for should also respect that option and the attached changes add that support.
