Changed content description for GEOMAR page

Removed reference to _content.html, added HTML for their planned
syllabus. Also added ,Germany to location because I didn't know where
Kiel was. (Kept wanting it to be typo of Kiev.)
Fixed broken list

I moved the sublist into the same <li> element as the headers in the
list of topics, for more correctness.
