[arch-dev-public] Replace Gentoo mime-types with Fedora mailcap?

After seeing bug 54977[1] I've been investigating where our /etc/mime.types comes from, and it's apparently from Gentoo[2] and hasn't been updated since Oct 2012. I would like to propose replacing mime-types with mailcap from Fedora[3], which is still maintained; it fixes the above bug. It also provides /etc/nginx/mime.types (conflicts with upstream NGINX, but defines many more types) and /etc/mailcap (not used by anything we have?). Thoughts? Objections? Should we also use the mailcap NGINX mime.types? [1]: https://bugs.archlinux.org/task/54977 [2]: https://packages.gentoo.org/packages/app-misc/mime-types [3]: https://pagure.io/mailcap/tree/master
