Title: Added support for reading the labels of curved yEd edges

I had some problems with graphml.read_graphml function discarding labels of curved edges, so i took the liberty of fixing it! :)

This commit makes it so that labels of curved edges, which were
previously discarded, are added to the graph just like straight ones.
