LibHTML: Implement basic tiled background image support

Browse source 
It's now possible to set a page background image via <body background>.
Also, HtmlView now officially handles rendering the body element's
background (color, image or both.) LayoutBox is responsible for all
other background rendering.

Note that it's not yet possible to use CSS background-image properties
directly, since we can't parse them yet. :^)
