+ In GradSmallStrainT, added additional field for the derivative of the plastic multiplier. With single field, RHS was not accumulated properly. Seperating this field into 2, the solution with C1 discretization of lambda WORKS!

+ In material GradJ2SS1D and GradC0J2SS1D, fGradientModulus_hh = E + k1 for both elastic and plastic
+ In material GradJ2SS1D and GradC0J2SS1D, once IP is plastic, remains plastic, so that solutions within the yield surface can be returned to the yield surface
