docker-image folder added

The docker-images where scattered across different files.
For faster access i moved them to an extra folder and linked them if they're needed elsewhere.
entries that where outside this folder and only contained basic documentation of the docker image where removed.

 Gitea is a selfhostable git server with a web interface.
 It is similar to Github but opensource.
 
+## Server
+
+A server can be setup via docker with the [gitea image](./docker-images/gitea_-_gitea.md).
+
 ## Client
 
 If you want to use all features in addition to the basic client described in
 [git.md](git.md) but don't want to use the web-interface all the time you can get
 [tea](https://gitea.com/gitea/tea) the official cli-tool for gitea.
