More useful for scripts...

Hi - I've added a few small features to your great simple ColourPicker, namely that it will take an optional colour argument ( colourpicker #fff, or colourpicker red, say) and it then outputs the colour at the end.  I think this should make it a usable tool in scripts, or from a text editor (VIM, say).

Is this helpful?

PS - I've not really done much GTK/C programming, so it's possible I've messed something up, I don't think so, but please tell me if I've done something silly. :-)
