Added object-name c-string getter function to basic objects so they can be referenced to free if dynamically created. (#754)

* Added basic object-name get for ASCII names to enable free if they were dynamically created. Added unit testing to validate the basic object ASCII object-name API.

* Removed static scope on character array used for name since the array gets copied into characterstring array and static is not needed.
