webgateway original_file_paths() displayed in webclient
Improved layout of FS-paths display
Tiny UI fix - Paths text-area at least 3 lines
showOriginalFilePaths() replaces countFilesetFiles() in template
get/countImportedImageFiles() in webclient_gateway.py

Since we are not porting these methods from FS work, we need to delegate to existing ArchivedFiles methods
