Let's Move In Together

Optimized the mod's code and metadata, and added a full Italian translation.
The mod has also been simplified into a single downloadable version instead of three separate versions. You can now choose and change its behavior directly in-game through Let's Move In Together Settings in the mailbox cheat menu. Your selected setting is saved and remains active after mod updates.
Fixed an issue where Sims who moved in together and formed a new household were always removed from their dynasty. They now correctly remain part of their dynasty after moving.
Fixed an issue that could cause the game to crash when Sims moved in together during a Stay Over (Growing Together) or while they were on vacation together.
The display conditions for the Ask to Move In Together interaction have also been improved. If a household only contains 2 adult Sims (+ children and/or pets, if any), the interaction will no longer appear, as it didn’t really make sense in that situation. The interaction will also no longer be available for certain special Sims, such as the Grim Reaper.
