#2705

• Added best-known solutions to the Solomon benchmark set.
• When the distance matrix is calculate internally for performance optimization, the DistanceMatrix-parameter is not set anymore, because this matrix is actually not part of the problem instance. This also fixes issues that qualities of known-solutions are wrongfully discarded due to a problem instance change that is actually not a change.
