Sam Atkins 6dcd8d4a2c LibWeb: Add support for "User" CascadeOrigin ...

User styles are applied after the UserAgent's built-in styles, and
before the Author styles that are part of the web page.

Because they're neither part of the page, but can still be modified
while the page is open, caching is a little tricky. The approach here
is to piggy-back on the StyleComputer's rule caches, which already get
rebuilt whenever the styles change. This is not the smartest approach,
since it means re-parsing the style sheet more often than is necessary,
but it's simple and works. :^)
