Fix Memcached::Rails read to allow nil options to be passed. #128

Closed joe1chen closed 11 years ago

The Memcached::Rails read method now allows nil to be passed in without throwing an error. Also, the default options value is now changed to nil instead of {} to match the behavior of ActiveSupport cache's read.
