      # Redefine the ActiveModel::Errors.full_messages method:
      #  Returns all the full error messages in an array. 'Base' messages are handled as usual.
      #  Non-base messages are prefixed with the attribute name as usual UNLESS they begin with '^'
      #  in which case the attribute name is omitted.
      #  E.g. validates_acceptance_of :accepted_terms, :message => '^Please accept the terms of service'
      #
      # Переопределяет метод ActiveModel::Errors.full_messages. Сообщения об ошибках для атрибутов
      # теперь не имеют префикса с названием атрибута если в сообщении об ошибке первым символом указан "^".
      #
      # Так, например,
      # 
      #   validates_acceptance_of :accepted_terms, :message => 'нужно принять соглашение'
      # 
      # даст сообщение
      # 
      #   Accepted terms нужно принять соглашение
      # 
      # однако,
      # 
      #   validates_acceptance_of :accepted_terms, :message => '^Нужно принять соглашение'
      # 
      # даст сообщение
      # 
      #   Нужно принять соглашение
      #
      #
      # Returns all the full error messages in an array.
      #
      #   class Company
      #     validates_presence_of :name, :address, :email
      #     validates_length_of :name, :in => 5..30
