Hi team,

The page PythonWikiEngines contains interesting projects to host wiki 
servers with Python. I would like to make the following changes to this 
page that was not updated since 2015:

- Add a project that you can test online at https://pwic.wiki
- Update several broken links
- Eventually cross check the list of projects with the ones listed on 
Wikipedia

The user account that I created for the above contribution is AlexBrea.

Thanks for your authorization!

Alex
