New Forum Index

Merged tracked threads and newest threads as tabs in addition to forum
category listing. Added experimental filter UI to newest threads. CSS
classes remains needed to be re-updated later as new init had too many
css classes & to ensure backwards compatible.
Septenary changed base font.

In my opinion Sans font are easier to read. Handpicked Noto from google.
SEO loads all by default.

Enabled auto loader (will fix query later).
