That should save some memory per node, and since creator has a lot of nodes
(e.g. opening the LLVM project adds about 1 000 000 nodes) this should be
noticeable:-)
Calling update inside ProjectTree::currentNode() and rename it to
findCurrentNode() to make sure it is an still existing pointer.
Also, try to reduce the somehow more expensive currentNode() calls
and sprinkle some const around that usage.

Getting the full list for a node can get quite expensive e.g. in
cases of recursive calls of QMakeProjectManager::findPriFile.
However, the FlatModel needs to decide quickly on whether an item
is editable to potentially allow renaming.
So split up QList<Actions> supportedActions() into individual
bool supportsAction(action) calls and make sure Rename is not
on the critical path.
