[pygtk] convert r,g,b color definition is a color name

[awalter1]

I've found the solution

First of all, the column containing the color in the ListStore have to be
changed from str to gtk.gdk.Color.
Then put the color in the column as follows:	
cmap = self.win.get_colormap()     # get any widget, just to have the
current colormap
color = cmap.alloc_color(r,g,b)

put the color in the related column in the ListStore.
that 's hit.
