I was going to remove all this anyway since we don't need it in sky, all sheets are local and there's no concept of a pending sheet now. I also removed the dirty bit I added to StyleSheetCollection. The bit is not correct and is preventing us from correctly processing sheets and invalidating style. I'll add it back later when I understand how to add the dirty bit correctly.
