Better Tagging
Improvement to the flag import to match flags created in the 3.1 exporter.
All masterplan creatures will now have:
flags.masterplan.imported = true
If the creature was imported with the 3.1.0 or later importer they will now also have
flags.masterplan.importerVersion.major, flags.masterplan.importerVersion.minor, flags.masterplan.importerVersion.patch
