Changes

The standard mod is a single '''package''' with manifest.sii file inside, description and icon files and the mod data files. The Workshop mod can and should consist of many '''packages''' - this change gives you possibility to create mods that are supporting few game patches updates without need to activate different mod by your mod users. In the '''versions.sii''' file you specify which '''package''' game should use when using the specified game patchupdate. But remember - this layout is only correct for Workshop mods. Standard mods are still using the one package approach.
