[meta] Improve documentation of config file
Note: This is a meta-task. It bundles several tasks together and is only closed once all these tasks are finished.
Improve the documentation of the config file. The current documentation places the information into a badly formatted table without options for extensions.
- #165 (closed): Re-formate RST output of config file parameters
- #166 (closed): Add XML tags for parameter changes by version
- #167: Write version information from XML files into RST output
