Revert "Optimize order of styles and scripts"

Revert "Optimize order of styles and scripts"

The patch did not improve performance. I'd like to think that the increased
control over when inline scripts are executed makes the patch worthwhile
regardless, but that is post hoc justification and possibly a bit of personal
ego. Krinkle agrees that we may use some of the ideas in this patch in the
future but he thinks we're better off not heading down this path before we
have a better sense of where we're going, and I trust his judgment.

This reverts commit e86e5f8460b922cadac231142a495f3259c67b43.
