CRHMcode GUI - Simulation not run correctly when start date and date of first observation don't match.

[jhs507]

When in GUI mode if the start date of a simulation and the first date of the loaded observation file don't match then the simulation is not run properly this is due to a bug in the CRHMmainDlg::RunClickFunction() on line 577

	int last = 0;
	for (int indx = Global::DTmin; indx < Global::DTmax; indx = last)
	{

		int next = indx + stepSize;
		if (next >= Global::DTmax)
		{
			main->RunClick2Middle(mmsdata, last, Global::DTmax);
			last = Global::DTmax;
		}
		else
		{
			main->RunClick2Middle(mmsdata, last, next);
			last = next;
		}

Because last is set to start a zero when it should be set to start at Global::DTmin

	int last = Global::DTmin;
	for (int indx = Global::DTmin; indx < Global::DTmax; indx = last)
	{

		int next = indx + stepSize;
		if (next >= Global::DTmax)
		{
			main->RunClick2Middle(mmsdata, last, Global::DTmax);
			last = Global::DTmax;
		}
		else
		{
			main->RunClick2Middle(mmsdata, last, next);
			last = next;
		}
