This version of the (renamed) _print_obj function uses introspection to
determine whether we're printing an Album or an Item. It's like function
overloading for Python! 😁
This is fixed by allowing MediaFiles to convert strings to integers on
assignment. An eventual complete fix will perform these type conversions in the
Item interface.
- Copying and moving are mutually exclusive. Moving overrides copying so the
user only has to add one line ("import_move: true") to disable copying and
enable moving in its place.
- Deleting is only possible when copying.
- Deprecating the "delete" option (moving is almost always better).
- Removed command-line switch for moving. It's somewhat "unsafe", so this
removes some potential for accidental irreversible changes.
- Changelog & thanks.
- Update docs to refer to import_move instead of import_delete as the
correct solution for ending up with only one copy of the file.
