Separate or hide the non-mg related NFTs from the chieves system

[luxumbra]

Is your feature request related to a problem? Please describe.
When I go to the Chieves UI at https://chiev.es and look at the prior NFTs, I do not like seeing the additional NFTs & roles that are not associated with MetaGame - Not-A-Cop, Cop Accustion etc. imo, these should have been created on a completely separate UI & contract to the MG chieves UI.

IMO it is confusing and inconsistent with the brand for a user visiting https://chiev.es to carry out MG business finds stuff relating to HotRocks. Likewise if someone visits the contract page on OpenSea, it shouldn't have non-MG related NFT displaying.

Describe the solution you'd like
I'd like to see the chieves contract redeployed, replaced in the app and only used for MG related NFTs

Describe alternatives you've considered
Hiding the NFTs from the UI would be one solution but they would still show up on OpenSea as NFTs minted on that contract and I don't think it looks great.

Additional context

There isn't a way to delete tokens because there's an incrementing id associated with each. The simplest solution would be to overwrite the metadata for these tokens with a new token.

I will look into adding you, @luxumbra, to the Superuser token for the tokens in question so you can overwrite them.

@luxumbra, I added you to the system-wide Superuser token, so you should now be able to do everything for all tokens.
