Subtle things:
* We now have shadow trees in NAC, inception! Only a couple lines of
code in the style system had to be changed to match :host rules and
so properly.
* Had to make highlighters.css contentaccessible, because otherwise we
can't load it from the shadow tree. I don't think it's a big deal.
* I removed some of the code from highlighters.css that claimed that
stuff inherited from the html element. That's just no longer true.
* Had to switch from `setAttribute("style", ...)` to `.style = ...;`.
This is needed because CSSOM from chrome code bypasses CSP (as
AnonymousContent did), but setAttribute() doesn't, see bug 1424474.
