bug 168 fixed (TheoryEngine::rewrite is not fully rewriting to a fix point); problem had to do with the builtin theory post-rewriting DISTINCT into an arithmetic term not in normal form. fix was to do DISTINCT rewriting in pre-rewrite. note that this doesn't add to the amount of theory rewriting work that needs to be done, because everything is cached
