L. David Baron bfbc629361 Bug 882573 patch 4: Make nsHTMLStyleSheet and nsHTMLCSSStyleSheet stop implementing nsIStyleSheet. r=heycam
Note that this removes the Reset method and the mURL and mDocument
members (and arguments to set them) from nsHTMLCSSStyleSheet.

On the other hand, from nsHTMLStyleSheet it only removes mURL (and
equivalent arguments), and nsHTMLStyleSheet keeps the SetOwningDocument
method that was previously part of nsIStyleSheet (but no longer virtual).
