Adding syncing github releases to pygame website releases.

[illume]

For #8

• Adds a youtube, github repo, and patreon link to projects.
• Github releases should be synced to the ones on the pygame website. So projects on github can just make their release notes inside github and not have to do anything to get the release onto the pygame website.
