Move out of Gitlab Wiki

I understand that this change is quite unreadable and hard to review, sorry for forgetting to do atomic commits. This patch does not change too much content wise, it just
* Gets everything from gitlab wiki
* Removes some specific gitlab hacks
* Formats all documentation file names to be in snake case so they look the same way as our code does

+# How to configure upstream proxy for federation
+If you want to proxify all http requests (e.g. for TOR) that pleroma makes to an upstream proxy server, edit you config file (`dev.secret.exs` or `prod.secret.exs`) and add the following:
+
+```
+config :pleroma, :http,
+  proxy_url: "127.0.0.1:8123"
+```
+
+The other way to do it, for example, with Tor you would most likely add something like this:
+```
+config :pleroma, :http, proxy_url: {:socks5, :localhost, 9050}
+```
