Summary: Really sorry for the size of the patch. It's mostly automatic s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to add the right namespacing and such. Overall it's not a very interesting patch I think. nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and nsIDocumentInlines.h into DocumentInlines.h. I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it. While fixing up some of the bits I also removed some unneeded OwnerDoc() null checks and such, but I didn't do anything riskier than that.
