Bags are loaded alongside the plugin and are stored in memory, and will never load again unless forced.
Bags will automatically be saved onto the server at intervals, which heavily increases performance compared to previous updates.
Players can now open and close bags, without ever having to force the server to read/write bag data.
This also means that Auto-Pickup should no longer cause high lag, on servers with many players.

Bonus: Only bags that have been changed are saved on auto-save to save resources.
