Implement CSS variables #5

It's likely they may need to use something clever like generics to work. Existing property values could be extended to take a CSSVariable, but for type safety, we need to make sure invalid types can't be provided.

We should be able to do something like CSSVariable<V: StringConvertibleValue>. Then it's completely generic. The only requirement is that the value can be converted into a string. In use, for something like a color property, it could be restricted CSSVariable<PropertyValues.Color>.
