Big List of Modpack Things

Also see the Modrinth Awesome list, and a (probably somewhat outdated) list of curse modpack downloaders at https://gist.github.com/jikuja/f44533a16ad04624c3eb8e99e7a3e494/

This list is a bit outdated in places, but I'm still adding things here so that I don't forget them.

Distribution platforms
