#6118 Automatic red, green and blue curve colors for oil, gas and water properties when using area fill

* Also removed green, red and blue from the cycled well log colors to avoid clashes.
* Only automatic when area fill is on.
* Potential color clashes for the general case with multiple Oil-curves in the same plot.
