Title: Use edge weight attribute as size if set when parsing gexf files

The parseGexf plugin sets a weight attribute for edges if defined. When displaying graphs, edge weight by default has no effect, since size is used to scale edge sizes.

This very simple approach sets edge sizes to existing weight settings, to scale edges based on weights.
