This patch adds the setProperty(name, value) API to CSSStyleDeclaration. Setting an invalid or empty value will cause the property to be removed from the declaration. Note that this only works on mutable declarations (i.e element.style) and not on resolved declarations (i.e window.getComputedStyle(element)).
