Migrating away from Simply

Simply is annoying. We wanna move away from them.

Things that needs to be solved before we can migrate:
* Simply is hosting our public webpage, and also our wikisite. These websites are built with PHP, which I know absolutely nothing about. We could probably figure out a way to host this on our new server, but I'm not certain it's worth the effort.
* Simply is right now configuring our DNS service, which is the thing making appendix.bleckhornen.org point to the new website. We need to use a new DNS service if we want to move away.
* We need to find a new mailserver solution. Emails to our domain (email addresses ending in @bleckhornen.org) are managed by Simply.

Right now the new Blindtarmen is hosted on [Oracle Cloud Infrastructure (OCI)](https://www.oracle.com/cloud/sign-in.html).

首先盘点 PHP 公共网页和 wiki 当前如何通过 Simply 托管，然后审查 Oracle Cloud Infrastructure 上新的 Blindtarmen 部署。确定托管、DNS 和邮件服务器的替代方案，并在网站、appendix.bleckhornen.org 以及域名邮箱不再依赖 Simply 时视迁移为完成。
