Use color gradient for intermediate best solutions

[HaaLeo]

Description

Currently in the CS and ABC algorithms the same color (yellow) is used to visualize the current best solution.

Proposal

To indicate the convergence of the algorithms the colors for the current best solution shall be retrieved from a color gradient. For example very light yellow to very dark yellow. With this change the user can easily understand how the algorithm converges.
