Adding Cleanroom Egg

[SodaSyrup]

Description

This is a crudely made egg for Cleanroom based on the Forge Egg. This made my life easier spinning up Cleanroom Servers by not having to first make a Forge Server and then adding Cleanroom and all that.

I dont have Pelican, so i wasnt sure how exactly to do an egg for that.
