Review of #2230: the skipped-image warnings were English text shown as is
in the result window. Skipped images are now data in the import and inspect
reports (`skipped`: image id and reason: missingFile, missingFolder,
missingRoot, incompletePath, masterSkipped) instead of warnings, and the
result window adds one line counting them through tr_format!, translated in
every UI language; the eight-warning cap is unchanged.
Reader-level tests now cover a missing folder and root record and a virtual
copy of a skipped master read from a catalog file.
