[Helma-user] JS-only stack traces

[Hannes Wallnoefer]

As it turns out, this solution didn't work with Rhino interpreted
mode. To make it work reliantly, I had to patch Rhino:

https://bugzilla.mozilla.org/show_bug.cgi?id=363058

This means no backport to helma_1_5. IMO this isn't a big deal since
1) it's just an enhancement (although a nice one), and
2) 1.6 is ready and should be better than 1.5.* in almost every aspect
anyway (i.e. there shouldn't be any reason not to update to 1.6).
