Commento with @souramoo's patches

I've patched Commento to fix lots of bugs and add new features!

Changes from upstream:

• NEW FEATURE: Auto refreshing comments with WebSockets for push updates
• NEW FEATURE: Guests can leave their name
• NEW FEATURE: Window title updates when there's new activity
• NEW FEATURE: Permalinks, and a subtle yellow highlight animation for new comments when they come in live
• NEW FEATURE: Smooth scrolling
• NEW FEATURE: Hide +/- if no children
• NEW FEATURE: Errors now slide down from the top rather than the ugly error system before (try upvoting your own comment after logging in!)
• FIXED: Twitter profile photo bug
• FIXED: Duplicate comment bug on login
• FIXED: Add target="_blank" to all external links, while also adding "noopener" to prevent XSS
• FIXED: Allow anchor links onto same page
• NEW FEATURE: Comment moderation dashboard, to approve/delete comments across your entire domain from one place
• NEW FEATURE: Press enter to log in after entering your password
