Facilatate writing clojure.core.test tests for slingshot exceptions

[hugoduncan]

When writing tests, it is common to want to check that a function throws in a given situation. Since the slingshot exception class is not fixed across clojure versions, and c.c.t's thrown? takes an unevaluated exception type argument, this is not straightforward.

The code I am currently using for this is https://gist.github.com/1966770

I've added thrown+? and thrown+-with-msg? to clojure.test's multimethod for test support. For getting the thrown object, recent versions of slingshot include get-thrown-object. Please let me know what you think.

Looks much better than what I had :) I didn't realise clojure.test was open coded like that.

fixed in 0.10.3
