.SYNOPSIS
  Cuit un mod d'assets et l'assemble en archive installable (lot H3b, Docs/Migration/16_H3_Mods_Paquets.md).

.DESCRIPTION
  Sources : ModSources\<Nom>\ (<Nom>.uplugin, Content\, Module\ ; voir Tools/ModSource.ps1).
  1. controles : plugin et module (MODULE_UNIQUEID = <Nom>), version de reference Releases\<Version>\Windows, aucun
     autre plugin dans Mods\ ;
  2. montage du mod dans Mods\<Nom>, cuisson DLC contre la version de reference (BuildCookRun -dlcname
     -basedonreleaseversion, via cmd /c : appelee directement depuis PowerShell, la version est coupee en deux),
     journal dans Saved\Logs\portage\mods ; remise en place dans ModSources\<Nom> dans tous les cas ;
  3. controle du conteneur : chaque paquet est sous Mods/<Nom>/ (aucun asset du jeu embarque) ;
  4. assemblage <Out>\<Nom>-for-LifePlay-<Version>\LifePlay\{Mods\<Nom>, Content\Modules\<Nom>} + notice bilingue,
     archive .zip testee (7-Zip) ; un assemblage precedent du meme nom est deplace (precedent_<date>), jamais supprime ;
  5. -Install <dossier du jeu> : copie le mod dans un jeu de test (dossier contenant LifePlay.exe).
