Title: make clone alias for dup

allow behavior to be similar to the behavior in Rails 3.1 where dup and clone do the same thing.

@ColinDKelley If you could code review this.
Also I know there are a couple more steps before this is done including possibly bumping the version.
Let me know what I might do there.
