[slicer-users] Add Second Locator/Tool to 3D-Slicer

Hi Pawel,

This message is given when the model file is not saved to disk with the rest
of the scene. But the locator model is actually constructed from scratch by
the module so just delete the "IGTLocator" model in the data view and then
re-add a locator in the OpenIGTLink module. To avoid the error, be sure to
select all models for saving in the File->Save dialog.
