Style Manager

A singleton instance of this class available via inkdrop.styles, which you can use to globally query and observe the set of active style sheets. The StyleManager doesn't add any style elements to the DOM on its own, but is instead subscribed to by individual <inkdrop-styles> elements, which clone and attach style elements in different contexts.
