Title: Remove tag method

I originally wrote the tag method as a shorthand so that when a cache had only one tag, it wouldn't be necessary to type ->tags(array($tag)). With the revision of tags to take strings or arrays, the tag function has become unnecessary--I'd suggest removing it before the launch of 4.1.
