Initial Individual Pose auto-save implementation

[HoloWise]

1. Adds an option in Settings for auto-save to save individual poses, default to true.
2. Adds FriendlyName to ActorFile - A unique name is needed for individual poses and currently present Name string seems to always be empty.
3. Adjust auto-save process, Scene auto-saves will now have their own timestamped folders, inside we'll place "SceneAutoSave.brioautosave" file that's same as previous timestamped brioautosave file and if enabled, individual poses in Poses folder. Individual poses are extracted from the actor list that's a part of the scene.
4. Adjust cleanup process to account for new folder based approach.
