340746 - make it possible to disable CSS parsing on iframe-specific basis

Status: NEW

It'd be useful (for parsing HTML in a hidden iframe never meant to be seen by users) to be able to disable CSS parsing for a specific XUL iframe.  As nsIDocShell has attributes for twiddling plugins, JavaScript, meta-redirects, subframes, and images, perhaps it's the appropriate place to expose a similar attribute for twiddling CSS loading and parsing.

This would be valuable for microsummaries, at least until we have some better way than a hidden iframe for parsing HTML, which we may well get out of bug 361449.

Minusing for blocking1.9; hopefully bug 102699 will make it and this will become unnecessary.  This doesn't seem particularly easier than bug 102699, and that's what we really want in the long term.
