Added two new external account settings to the site: GitHub and Patreon

Hi all, when you access your settings on the main site, you'll now have the ability to add two new social accounts/external sites to your profile.

I thought it would be nice to add something for our scripters who like to share their source code, so I've added a GitHub account icon to the list - you can see a preview of it on my profile.

For those that accept donations through Patreon, I've added it as a donate button in the same style as the PayPal button. You can see it in action on the profiles of KAFAROS and Quechus13.
