File versions

To protect against loss of fidelity when opening documents in an older version of Dune 3D than they were created with, documents include a version level.

This version level is distinct from the application version and is only incremented for changes that are incompatible with older versions.

Forward compatibility, as in being able to open files that were crated in an earlier version, is always given.
