Naive patch

As Darin has suggested, I moved the code that sets the
hover/active/inActiveChain bets out of RenderLayer into DocumentImpl. While
doing this, I introduced a couple of possible over-simplifications:

1) The new code walks up the DOM tree directly instead of walking up the render
tree and looking up the corresponding elements. I couldn't figure out the case
where this makes a difference (despite the comment about CSS3 ::outside).

2) The old code had a separate mustBeInActiveChain boolean, theoretically
allowing for nodes not in the active chain to become hovered and active while
an active chain existed. Again, I failed to come up with a case where this
could actually happen (needs a non-readonly NodeInfo with the mouse button down
which is not a mouseMoved and is not the initial mouseDown).

Hyatt wrote the current hover/active code so he's likely to know what cases I
missed.
