snappyHexMesh: Simplified and rationalised the region refinement level specification

Browse Source 
The inside or outside region refinement level is now specified using the simple
"level <level>" entry in refinementRegions e.g.

    refinementRegions
    {
        refinementBox
        {
            mode    inside;
            level   5;
        }
    }

rather than

    refinementRegions
    {
        refinementBox
        {
            mode    inside;
            levels  ((1E15 5));
        }
    }

where the spurious "1E15" number is not used and the '((...))' is unnecessary clutter.
