MootDACH23: Short answers allowing typos with STACK

Typos in the "short answer" question type are currently hard to catch, you'd need to find all different misspelled (mispelled?!) versions
STACK also offers string answers and can do "math" on it. One such "math" way is the Levenshtein string distance, which can measure word similarity. It is used in many state of the art spell checkers.
This works well and is useful outside of maths (or STEM in general), e.g. you could ask "Name the river in Mark Twain's Huckleberry Finn" and accept all misspellings of "Mis(s)is(s)ip(p)i" at once.

The discussion showed that it might actually be best to improve the "short answer" question type itself to allow this functionality! If someone has the resources to change the short answer question type, I think doing it this way is actually the right way.
