View source for LOR model names

'''Nutcracker/LOR tip.''' 
Please do not use !@#$%^&*()<>/\}{, characters in your model names. Dash works fine though. I'm helping a user move over 150 models from LOR to NC and was having issues. Getting rid of those characters solved the issue. I don't know which one of those was causing the issue but he had ,/&\ in some of the model names.
