Add world restriction to rank StatsRequirements

[wyattduber]

Hello,

On our server, we currently have a rank system that has, among other things, a lot of gameplay stats requirements to rank up. Killing mobs, crafting items, mining certain blocks, etc.

The issue is that we also have a creative world along the main survival one that players can go and play in. Because there is no world restriction for stats requirements, players can go into this world and break as many required blocks as they want or craft as many items as they want, etc, to instantly complete those requirements.

I'm wondering if it would be possible to add a world restriction to rankup or specifically stats requirements to restrict what worlds you can be in to be credited for those requirements.

It would also work for us specifically to have a gamemode restriction as they can only get into creative in that world. But I think a per-world restriction would be cooler for other servers that have special survival worlds, like a kitpvp-only kind of world.

Thanks!
