Title: Add URL to Wikia Extensions and $wgExtensionCredits to some that were missing it (2)

The original pull request is found at https://github.com/Wikia/app/pull/5745 . It was reverted due to breaking the dev branch and I have fixed the syntax errors. I probably ended up trying to merge the changes wrong, but it appears to have worked so I hope that isn't an issue.
