Session_Store/Redis.rb uses hash arguments which is not a ruby 1.9.2 feature.

The README states that rack-cas requires Ruby 1.9.2 or greater. However, the Redis.rb file uses hash arguments in the self.write method. Not sure if the Readme or the method itself should be updated but I thought this was worth pointing out for folks running legacy ruby version apps (like myself 😆).

Good point. Thanks @bynarlogic. I think at this point we can bump up the minimum version. So I'll update the README.
