[Feature Request] Savable Dictionary Saved Per File

[TechniPoet]

Instead of a single dictionary of <string, ISavable> there should exist a dictionary per file.
This would allow each file to contain savables of the same key to exist while not requiring unique key modification.

Instances where this could be useful:

• custom or preset settings, each as it's own file.
• per player data
• common file metadata
• save slots
• easy save rollback implementation
