[1.4.0] Implemented background-image, background-repeat and background-attachment CSS properties. background shorthand property HAS NOT been extended to allow these, and background-position IS NOT implemented yet.

- Also: fixed up some flaky behavior in list-style shorthand, introduced uri_or_none
