[PATCH] colorBy=status should use fixed colours

[falkb]

This little patch sets fixed colours if you choose colorBy=status as chart option. It's a user request here because they were confused and didn't realize why the colours changed from time to time, and they wished they can accociate a certain state with certain fixed colours. (Remember, currently _buildMap(colorBy) traverses the tickets and simply increments the colour in the map by the states it finds first on its way through the tickets). Note, I use a hard-coded state<->colour mapping as desired here:

Thanks for the patch. More flexibility in color choices is good. I don't know that I'd accept this patch into the main line but I would use it as the conceptual basis for adding configurable coloring.
