Modify the implementation of ListDigraph::ArcIt (#311)
The new implementation is based on out-arc iteration (like
ListGraph::ArcIt) instead of in-arc iteration to make it
consistent with the documentation.

Much better implementation for node splitting (#311)
in ListDigraph. This solution is the same as the one that
is used in SmartDigraph. It is much faster and does not
invalidate any iterator like the former implementation.
