/kbin RTR#16 Update on kbin.social, performance improvements, considerations for enabling API en (kbin.social)

Today, with the assistance of @piotrsikora, we've updated kbin.social. I also implemented a few fixes that should improve the site's performance. I'm still waiting for a few metrics, and then I'll try to enable the API (Piotr will probably want to strangle me when he finds out I want to do it over the weekend ;-))...
