crystallite: 

added full check whether residuum in inner loop is NaN
SingleCrystallite now takes/stores Lp guess

CPFEM_Taylor (missing in GIA!!):
former fully plastic guess for Lp has been exchanged by keeping the last converged Lp (global array CPFEM_Lp) to serve as new best guess for the next time step. This speeds up the inner loop of TimeIntegration.
