Currently, inspector binds scripts to resources and attempts to show them
within a resource context. However, for a script that was added dynamically
(e.g. via document.write() or by adding a script element), we're unable to
display script in a resource. 
Thus, it is suggested that inspector should handle dynamically added scripts
differently. To enable this, we would need to pass some indication to inspector
that a script was added programmatically. As scripts written with
document.write() are created from within HTMLTokenizer, it is suggested that we
add a field (e.g. processingDynamicContents) to HTMLTokenizer and, whenever a
document is opened from script, create HTMLTokenizer with
processingDynamicContents set. This, in turn, would require adding a similar
protected property to Document that would be used to pass a flag from
Document::open() to HTMLDocument::createTokenizer().
