FEATURE: Improve GitHub commit, PR and issue onebox rendering

Bump onebox version to include new github rendering, and add relevant CSS

Avatars are reduced in size significantly, and icons are added to easily differentiate PRs and commits. The 'Issue:' prefix is removed from issue oneboxes, to make them consistent with commits and PRs.
