Migrate to MkDocs

[honzajavorek]

See the website at honzajavorek.github.io/mkdocs-python.cz.
This is a proof of concept and a work in progress.

Goals

• Give up on complicated custom solutions which have little added value, but enormous overhead
• Give up on custom design, because there is nobody in the community to maintain custom designs
• Use as much existing software as possible
• Make the website easy to maintain, easy to edit, easy to contribute

Intentionally not trying to achieve feature parity with existing python.cz website.

TODO

• port static content
• customize the theme
• events as a plugin
• fix absolute links and make them relative
• icons (index is here: https://emojipedia.org/twitter)
• images
• legacy redirects
• analytics
• english version
• delete the old code
• use https://github.com/juniorguru/teemup to get events from meetup.com
• keep tests which make sense and delete the rest
• better readme
• triage https://github.com/pyvec/python.cz/issues and close all irrelevant issues
• update https://docs.pyvec.org/guides/calendar.html and link it from the site
• create issue (nice to have): social cards - https://squidfunk.github.io/mkdocs-material/setup/setting-up-social-cards/
• create issue (nice to have): logo should be on a white circle
• create issue (nice to have) for each of the TODOs in the page content
