Add clojure.core/pattern? predicate

Question

Just like http://dev.clojure.org/jira/browse/CLJ-1719 , this helps with clj/cljs compatibility.

Comments

Rather than the name `pattern?`, I'd suggest the name `regexp?`, for consistency with ClojureScript (which has long had this function).

Whoops, uploaded wrong patch. Tests actually pass in this v02 patch.

I added a patch that uses `regexp?` to match Clojurescript's existing predicate.
