Title: Symbol case for #check_box_checked? helper

Symbol is not currently a case. The else statement calls #to_i on value and in Ruby 1.9.3, Symbol has no #to_i method.

Also, please close https://github.com/rails/rails/pull/8991, I accidentally sent the first version of this pull request to master instead of 3-0-stable
