Use WebCore's built in support for user styles

Use WebCore's built in support for user styles instead of the
hack we were doing before.

This has a side-effect of fixing a bunch of content-interaction
bugs because we will be using real user-level styles (in the
CSS sense) rather than content-level styles.
