* Change setup_en.md to use Latest releases page
Really simple change to point users to the Latest release page instead of the Releases page. Saw a user accidentally download 0.3.6 because it was the last item on the page (they're accustomed to scrolling down to the bottom of the page in GitHub for the Assets section), and this change prevents that outright.

Rewrite text and link to restore semantic compatibility.
* rework main ap setup guide
* review updates
* add blurb about re-opening rooms and user-content
