Subject: [PATCH] turbulenceModels/laminar::Maxwell: Updated handling of single
 mode

A single mode may now be specified either with the 'modes' list containing a
single entry:

        // Example 1-mode specification
        modes
        (
            {
                lambda          0.01;
            }
        );

or by specifying the 'lambda' entry without 'modes'

        // Single mode coefficient
        lambda          0.03;

If both are provided the 'modes' entry will be used and a warning about the
unused 'lambda' entry printed.
