A simple client-side utility mod that keeps the server ResourcePack always loaded.
Not everyone has a beefy PC, so having ResourcePacks loading and unloading everytime you join/leave the server is painful.

This mod also caches the latest server ResourcePack and loads it when the game is starting.
The result is the player having to load the ResourcePack only one time.

The main focus of this mod is modpacks with a server included, so they can keep the resourcepack on their server instead of inside the modpack (making it easier to update), without making the life of their players harder.
