Subject: [PATCH] feat(pptx,ui): retentative mauvaise ecriture pour PowerPoint
 + lien liste RTL interface

- PowerPoint beneficie du garde-fou de retentative (arabe livre pour du
  persan etc.), comme Word, Excel et PDF
- l'interface : la liste des locales RTL renvoie desormais explicitement
  a la reference serveur (core/languages.py) pour eviter tout oubli
  lors d'un futur ajout de langue d'affichage
