Extend randomization of multiple alternatives for cases, where one alternative must be "true"

Certain evaluation schemes for multiple choice questions require that

at least one alternative must be true. Otherwise, a division by 0

might appear.  This is an issue, when a subset of alternatives is used

(e.g. 3 out of 10 alternatives). The version know evaluation schemes

with such a requirement and makes sure that in the resulting set, at

least one correct alternative is correct.  Note: this change does not

make sure that the full set of alternatives contains at least one

correct alternative.
