Subject: AMBER: Bug: ptraj adds spurious box information

According to Appendix E of the Amber 8 Manual, box information should be
written to traj files only for periodic systems, and indeed, this is how
sander behaves. But ptraj, given a parm file for a non periodic system
(i.e. one in which IFBOX=0), produces an output traj file with spurious
periodic box info given as three zeros.
