Course teaser

Course steasers should be able to be used in any combination of columns.

It should be possible to define in the plugin that only courses from one area should be displayed. 
For example, on a subpage on the topic “A”, only courses with the tag “A” should be displayed.
All applicable courses should always be displayed, no limit to the number.

The courses should be sorted by date, the course taking place next is always at the top.
