Popular runtimes (V8[1], SpiderMonkey[2], IE[3]) support a `stack` property on Error objects to get the error's stack as a string. This change adds support to otto for this same feature. It's implemented in a similar way to V8, using a getter function. This avoids generating the stack trace (which is done in a loop with string manipulation etc) unless the user requests it. There's no standard, or even trend, for the actual _content_ of `stack`, so we basically just copy what V8's traces look like.
