LibHTML: Add LayoutNode classes for "display: list-item" and its marker

Browse source 
This patch removes the hard-coded hack for "display: list-item" from
LayoutBlock and adds LayoutListItem and LayoutListItemMarker.

Elements with "display: list-item" now generate a LayoutListItem, which
may then also generate a LayoutListItemMarker if appropriate. :^)
