Log:
Fixed the memory management semantics of GeglNode's, they are
reference counted. If they are created by a parent the parent
holds the initial reference, and doing a manual un_ref on the
node will break it free from the parent, if this is not done
the node will be destroyed when the parent itself is unreferenced
the last time.
