saving NMR ensemble pdb with [NAME] only saves last structure

saving NMR ensemble pdb with [NAME] only saves last structure

example:
open 1plx
save [NAME].pdb mod #1

Saving without using [NAME] saves the whole ensemble, whereas the above only saves the last submodel (80th of 80) instead of all of the submodels.

The way the code currently works is that it goes through the models specified and creates [NAME].pdb for each of them. Since the NMR structures are individual models, they overwrite each other, with the last one "winning". Will try to smarten up the code.
