Changes made for Pathfinder V5 PC's.

The csproj now references JornsHyperDriveFlex4Frame.ConfigurationOverrides.json instead of the deleted .ConfigurationStore.json. This means the override file will be copied to the output directory during build, and the CreateDefaultSettingsFile() discovery logic (which scans for both .ConfigurationStore.json and .ConfigurationOverrides.json files) will pick it up as an available machine configuration.
