same effect, less code

attr_accessible is inheritable, don't warn if a parent is protected

class Protected < ActiveRecord::Base
	attr_accessible :column
end

class Unprotected < Protected
      # can only assign column here
end

the problem was the methods were not being processed
the same as regular controller methods, causing them
to have a :scope node, creating a new scope when
the ControllerAliasProcessor did not expect it. This
caused the variables from the method to not be propagated
to the view.

for consistency

If a file in app/controllers does not contain a class, treat it like a
library.

Test with 1.9.3 on travis-ci
