A simple control with pattern like we have since years , why remove the good part ?

pattern="^([a-zA-Z0-9]*|OLDCODE)$" for subquestion
I think we need only pattern="^([a-zA-Z0-9]*)$" for andswers

We already validate duplicate : but it's only for duplicate …

It can be great to NOT delete whole, but really update existing, delete deleted and add new.

Idea :

1. Use the qid set in subquestions for updating
2. Get the array of subquestions->qid set, delete all other with parent_qid
3. Add the new one
