#24 few rendering fixes towards web standards

[x_gen]

A tiny step towards standards:

style rel="appendix stylesheet" now recognized
(for acid2 test)

background:none did not override background-color and background-image, now it does

scrollTo(node) scrolled to the top of the bounding box including margins. With acid2 test where margin-top is > 2000 pixels, clicking "pass test" jumped to white nirvana. Now jumps to the picture pretty like firefox.

BTW, I appreciate your efforts, a pure java browser is a must-exist.
