dependent => :protect option

Adds a new option :protect for the parameter :depends from has_many method. This option forbids destroying records with associated records in a association created with :dependent => :protect option, more or less like ON DELETE RESTRICT SQL statement. If you try to destroy a record with associated records it will raise a ActiveRecord::ReferentialIntegrityProtectionError (defined also in this plugin).

Based on the idea and the code from diego.algorta@gmail.com in Ruby on Rails ticket #3837 (http://dev.rubyonrails.org/ticket/3837).
