setParameter/updateParameter integration

[MassimoPetracca]

• add setParameter to ShellMITC4, forward it to all sections

int ShellMITC4::setParameter(const char ** argv, int argc, Parameter & param)
{
	// this element does not have specific parameters
	// just forward it to all sections.
	// therfore we don't need to implement updateParameter
	int res = -1;
	int matRes = res;
	for (int i = 0; i < 4; i++) {
		matRes = materialPointers[i]->setParameter(argv, argc, param);
		if (matRes != -1)
			res = matRes;
	}
	return res;
}
