GLM2 update.

updated behavior when computing multiple lambda: all user specified lambdas ( < lambdamax) will always be computed, do not stop when not improving.

updated GLMMovelView to include table with all lambda values and ability to show any of them.
 + added option to view confusion matrix at any (computed) threshold.
