Commented Unassigned: All properties (A, R, G, B) in GraphvizColor class gets color from a field [25569]

Code from GraphvizColor.cs:
```
public byte A { get { return this.a; } }
public byte R { get { return this.a; } }
public byte G { get { return this.a; } }
public byte B { get { return this.a; } }
```
change it to:

```
public byte A { get { return this.a; } }
public byte R { get { return this.r; } }
public byte G { get { return this.g; } }
public byte B { get { return this.b; } }
```

Another issue with this: it seems that these colors are formatted as "#RRGGBBAA" in the generated .dot file, but from what I can tell, Graphviz doesn't understand the "AA" part, so it doesn't render the color. I tweaked it to format the colors as "#RRGGBB" (as well as fixing the original bug described above) and it started working.
