Update :noscript children declaration

`<noscript>` has a little more valid children than just `pcdata`. This
will allow more elements than is appropriate, but it’s better than
over-validating.

Errors thrown inside __toString() produce a basically unusable stack
trace. Switching it over to using `toString` instead (and just calling
that from `__toString` for backwards-compatability) gives you a much
nicer stack trace.
