Subject: [PATCH] fix: find a scenery's i18n tables whatever the case of their
 names

The i18n folder and its <scenery>_<language>.json tables are looked up
through CaseInsensitivePaths, so on Linux a scenery's texts are translated
when the table is named in other letter case than the scenery file.
