Title: Add support for Memcached::Rails write option :unless_exist

Fix Memcached::Rails write method to match ActiveSupport memcache write behavior:

1) Support :unless_exist option (don't write value if key already exists).
2) Convert values to string if :raw is true. This allows values like Fixnum's to be passed into write.
