This allows the LINQ spelling to be used, but benefits from the performance improvement of the specific methods for these classes that provide the same result.
This rule no longer appears to be buggy, so enforce it. Some of the automated fixes are adjusted in order to improve the result. #pragma directives have no option to control indentation, so remove them where possible.
Previously the StartGameNotification and MusicPlaylist traits used the IWorldLoaded interface to play an audio notification and begin music when the game started. However this interface is used by many traits to perform initial loading whilst the load screen was visible, and this loading can take time. Since the traits could run in any order, then audio notification might fire before another trait with a long loading time. This is not ideal as we want the time between the audio notification occurring and the player being able to interact to be as short and reliable as possible.
Now, we introduce a new IPostWorldLoaded which runs after all other loading activity, and we switch StartGameNotification and MusicPlaylist to use it. This allows timing sensitive traits that want to run right at the end of loading to fire reliably and with minimal delay. The player perception of hearing the notification and being able to interact is now much snappier.
Disabling the shroud is sufficient to allow seeing the map. This fixes a game with the "Explored Map" option enabled. Previously using the `/all` command twice to toggle it on and off again would also reset the shroud, causing the map to no longer be explored. Now, using it twice will cause the map to remain explored, as intended when the "Explored Map" option is enabled.
