[shadow-styling] alternative idea.

(as an alternative to this: http://dev.w3.org/csswg/shadow-styling/)

Let's imagine that we have @-rule named @shadow that defines block of
rules applied to the shadow tree of some element:

@shadow dropdown-select {

   :host > caption { ... }
   :host > button { ... }
   :host > popup-list { ... }
   :host > popup-list > option { ... }

where :host is the element it is applied to. Essentially
@shadow {} defines style set of sub-tree that is rooted to the host element.

To apply that shadow styling to the element we can add something
like 'shadow' property so this:

select[size=1] {
  shadow: dropdown-select; /* name of style set */

will apply @shadow dropdown-select to the shadow three of matching
<select> elements.

This schema does not require any new entities or syntax constructs:
we have @-rules already, so it is a matter of adding new property.
