Newton: fail earlier

Browse Source 
i.e. give up after 10 instead of 15 Newton iterations. since this now
also causes the CNV convergence criterion to be ignored after 8
instead of after 13 Newton iterations, and because CNV stagnation
seems to be the cause for the vast majority of the failures, it does
not lead to worse results or more time step chopping on Norne but
causes fewer wasted iterations.
