CSS should support inclusion of resource

Currently, CSS-based skinning can require two files - an LZX file that includes different resources and a change to CSS file that links view to new resources.

CSS compiler should support inclusion of filesystem path in CSS -

[name='controls'] basebutton[name='close']{
    closeresource:"gloss_blue_windowcontrols_close.jpg";
}

and possibly http relative and/or universal paths -
/* contact item elements */
contactitem [name='contactitembknd'] {
    resource:"http:resources/gloss_blue_listitem.png";
}
