LibHTML: LayoutText should always use parent's style properties

Browse source 
This patch makes StyleProperties heap-allocated and ref-counted so that
a LayoutNode can be without one. The ref-counting also allows anonymous
blocks to share style with their parent block.

LayoutText never needs a StyleProperties, since text always inherits
style from its parent element. This is handled by style_properties().
