Default edge color not set after loading .dot files

[Dimitris Kalamaras]

1. Save this network to some file directed.dot:

 graph graphname {
     // This attribute applies to the graph itself
     size="1,1";
     // The label attribute can be used to change the label of a node
     a [label="Foo"];
     // Here, the node shape is changed.
     b [shape=box];
     // These edges both have different line properties
     a -- b -- c [color=blue];
     b -- d [style=dotted];
 }

2. Load directed.dot in SocNetV. All network edges appear blue. The default edgecolor should be changed to blue.

3. Create a new edge by mouse (middle/double clicking). The new edge takes the previously set initEdgeColor (default: black) rather than the color set by the network file.
