This refactor splits the import and export functionality out of the ImportContext and adds an ExportContext. This also introduced separate importer and exporter implementations.
Additionally, adding archive, save, scripts, and server files to the final export archive has been implemented at the exporter implementation for each instead of handling it in the context. This should be a good pattern if other files need to be added down the road.
- Fixed circular DI issues with importers and importer context
- Added additional mappings for data <-> manifest models
- Avoid null reference exceptions when trying to export archives/media where files don't exist
- Consolidate import dialogs
- Render selectable flags in export dialog
- Fixed various media uploaders to use new MediaService.WriteToFile
