Create an editable start page

[mariobehling]

At the moment there is no editable start page with information about the event. Please create an editable start page similar to other platforms. In the admin area add a page to edit the images and text of each section.

Hopin used to have a nice page, e.g. here https://web.archive.org/web/20210831232426/https://hopin.com/
Instead of black use blue and gray as it fits, e.g. compare here https://web.archive.org/web/20210401021004/https://hopin.com/

Ensure to include a section with "events"
