Fixed Flame Tree, updated banner.

Added a live indicator for Twitch and a fix for halidom calculator's material count being too close.

Added meta description and fixed duplicate link.

Overhaul of website. Known issues: Firefox does not support backdrop-blur as of now. Fallback is a solid color or complete transparency, which makes the interface look noticeably worse. Tested in: Chrome 79, Safari 13, Firefox 72. Performance hit in creators page. Rainbow accent works differently between browsers, not a priority issue.
