[sudo-discuss] Update donate button on sudoroom.org

I updated the donate button on sudoroom.org so it now let's you do either a one-time credit card donation + has a link to sudo-humans for recurring. We should set up paypal as well if people want to give us that. It would also be nice to have recurring payments without needing a sudo-humans account. If anyone feels like adding that to the wordpress. -- marc/juul
