trunk: changes to Dan's neural net setup, with new preconditioning method (speed roughly doubled if you use train_pnorm_online.sh, which uses the new preconditioning method).  Various bug-fixes, optimizations and cleanups in matrix code, cuda-matrix code and thread code.  Still tuning this so recipes not checked in yet.
