Created a runtime hook to handle DOM nodes. Specialized ubi::Concrete for nsINode-inheriting objects. Displayed outgoing nsISupports* edges on reflector JSObjects. Generated outgoing child edges from nsINodes by examining their children. Updated the UbiNodeCensus to ignore zone checks if there is no zone to be found in a node. --HG-- extra : rebase_source : 319dccb3277a39e51a79588eac9c8f2b4ff97c2f
