Field for default negative value in Matching Questions with n:n matching

1 Requirements

The question type Matching Question in the current version of ILIAS allows not only for matching pairs against each other, but also for matching more than one term to more than one definition. To give these matches the appropriate results, the person creating the question now has to assign a value to all possible matches to prevent the students from just matching all terms to all definitions. This leads to an exponential increasing amount of values to assign and makes this type of question, while being a nice feature in itself, quite unusable for bigger amounts of terms and definitions.
To solve this, there could be a field to set a default value for all not defined matches, that could than be set to a negative value so only the right matches have to be configured.
This problem was also discussed in the bugtracker.
