The idea behind NodesWatcher was that it was the central place to catch node related signals, so that users didn't need to connect to each individual node and the nodes didn't need to be QObjects. Somehow Nodes ended up being QObjects anyway. Both the recently added ProjectTree and the FlatModels consume the signals the NodesWatcher sends. Unfortunately there's a ordering dependency between the ProjectTree and the FlatModels. This patch removes all NodesWatcher and instead makes the ProjectTree singleton the emitter of various project tree related signals. The ProjectTree also ensures that the ordering between the FlatModel and itself is taken into account. And it makes Node not derive from QObject, saving some memory in that process.
