Replace old multi-dispatch tests. Multi-method dispatch is now in a separate test file, added yesterday. 51-multi.t will now just test multi subs. Needs more tests, but does cover arity based dispatch and that the proto functions as it should - being called first then delegating to the multi-dispatcher.
