non-convergence still needs to call budget routines

[emorway-usgs]

In the Sagehen example, with it running all the way through as of 10/23/17, there were roughly a half-dozen time steps that didn't converge but the budget routines are not being called. To fix this, the order of these two if statements should be switched in the custom code:

if (!MS_GSF_converge)
{
    afr = false;
    MFRunYet = true;
    //MODFLOWConverge = CheckOscillating(MF_Segs);
} else
{
    gsflow_prms(ref Process_mode, ref afr, ref MS_GSF_converge, ref Nsegshold, ref Nlakeshold, MS_Flows, IDivert, EXCHANGE, 
                DELTAVOL, LAKEVOL);
    afr = true;   
}

if (myModel.mInfo.Iteration > myModel.maxit)
{
    Console.WriteLine("Ran into maximum number of iterations - Warning !!! models have not converged.");
    MS_GSF_converge = true;
}

However, this resulted in many more time steps not converging. I undid the change for now, but we still need to get to the bottom of this issue.
