Peer to Peer Payments

[mikhael28]

Right now, we have a system set up to allow players to pay each other out using MetaMask, and Ethereum wallet.

First, we want to update the UI on the buttons to mark the MetaMask payout. Then, we need to review the process of linking the MetaMask wallet to the site - that and the payments functionality had all worked in the past, but it needs review.

Second, we need to actually mark that the payment was 'completed', on the Match db object, and then to hide the button if the payment was transacted as completed. This will require some sort of callback from the MetaMask wallet, to then trigger the API call. API route already works, just need to structure the JSON body.

Third, we need to give the Stellar GC payout version. This will involve setting up a new lambda function, to facilitate transfer from one wallet, to another. We will need to run XLM checks to make sure the transferring wallet has the XLM to perform the transaction. This is related to #13 ticket, migrating off Stellar test net.
