Keep a copy of older version of password protected VIs during upgrading to newer LabView version

[mfattahi]

Password protected VIs can be imported and saved to a newer version of LabView. However, the password protected VIs can't be saved to a previous version of LabView. I am suggesting for LabView to keep a copy of the old version of password protected VIs and give a warning during upgrading to a newer version in case one has to convert to an older version.

This is functionality that is best served by a source code control system, not LabVIEW.
