[WIP] Index navigation improvements - EP04

Once again, opening this to contain any discussion/feedback.

This is in LATEST builds.
https://github.com/MayhemYDG/4chan-x/wiki/4chan-X-LATEST

The goal is to replace the official catalog.
In a **future** 4chan X version, support for the official catalog will be completely removed, saving a good amount of useless code.
