Critical bug fix in SmartDigraph::split()

Description
The following code causes "Segmentation fault" error in the 1.0 release as well as in [9194a12c52e6].
typedef lemon::SmartDigraph Digraph;
DIGRAPH_TYPEDEFS(Digraph);
Digraph G;
Node n1 = G.addNode(), n2 = G.addNode(), n3 = G.addNode();
Arc a1 = G.addArc(n1, n2), a2 = G.addArc(n2, n1),
a3 = G.addArc(n2, n3), a4 = G.addArc(n2, n3);
Node n4 = G.split(n2);
The attached patch [99dcd99637ba] fixes this critical bug on the top of [9194a12c52e6]. However I think it would also worth to merge into the 1.0 release branch.

Replying to kpeter:
Bugfix changesets should be applied on the top of the "last common point" of the affected branches. See MakingRelease and the this post on the lemon-devel list for more details. (BTW these information should probably be put on the CommitGuides page instead).
So, I transplanted your patch on the top of [6dbd5184c6a9], the result is [00c8843d491d]. Then I merged it to both branch, of course.
