This code resets a bot's nickname in all the guilds it is in, with a delay of 2 seconds between each guild to prevent rate limiting.
This code will take tokens from a .txt and replace the word token in the index.js file with each token from the list, saving it to it's own token.js file (token1.js, token2.js, token3.js, and so on) to remove the manual labor of it.
