New way to add all tokens to Metamask

[sidko]

Current Problem
Users who use the exchange need to add their social money tokens one at a time. This is time confusing, complicated, and hard to do even for experienced users (also, we don't make it easy to see the token address on our apps).

Describe the solution you'd like
Dan Finley at Metamask tweeted about this: https://metamask.github.io/metamask-docs/Best_Practices/Registering_Your_Token. Seems like we can implement this on our end. Let's start with the exchange and then add to the app.

On the exchange front, we can add all social money token that are traded on the exchange to their MetaMask.

CC @rachel-tryroll to help with a quick design of the button here.
@marlon-wiprud we may need to check if the uses has connected their MetaMask and only then show the button.
