Weird package combinations should be cleaned up
While preparing #150 (closed) I realized that we install the parskip package, which is totally obsolete when based on KOMA-Script. Funfact: It's only included in bfhthesis but not the other templates.
That should be removed and the documentation checked, why this was the case.
Beside this, the patching for \blindtext
can be simplified using hooks and should probably be marked as an optional section in the template.
