ProjectNodes: Do not derive Project Nodes from QObject

Browse Source 
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.
