mob_lists -> player and client lists

[Posshum]

About The Pull Request

Improves various lists to respect the joined players list, and normal player list (client mobs that have been played in-round and client mobs respectively).

Developer's checklist

• Try to modularize as much as possible.
• Mark the start and end of edits outside the caustic modular folder (if applicable) for changes made.

• Ensure that it compiles locally, and test new features (when applicable, please record if not!), or potential issues with related features.
