feat(web/converse): Import repository
Imports the converse forum software I wrote a few years ago. I want to clean this up a bit and try using Hotwire with it. Note: The original repository was AGPL-3.0 licensed. I'm the copyright holder and have relicensed it to GPL-3.0 in the commit that is being merged. Imported from: https://github.com/tazjin/converse git-subtree-dir: web/converse git-subtree-mainline:386afdc794git-subtree-split:09168021e7Change-Id: Ia8b587db5174ef5b3c52910d3d027199150c58e0
