Remove the CSS Properties API

Remove the core/css/properties/ folder, since it's currently dead code.
Will re-add when the Ribbon project starts up again.

- * CSSPropertyDescriptor object, which stores resolved function pointers.
- *
- * To add a new property, create a subclass of CSSPropertyFunctions and implement

- *
- * No property-specific logic should exist in the style engine outside of this class.
