Moved to Hugo

Finally migrated most content from my old page to Hugo with Academic Theme to get up to date with my homepage. Main reason was to have a maintainable homepage again. Drupal used to be a great tool also for smaller websites, however in recent years it became apparent that it takes to many resources, in terms of time, attention to security updates and server requirements, that I decided to move on. If you see some obvious rough edges here or there, please drop me a line.
