Quiz

Hello,
Just to let you know that I have added backup/restore to renderedmatch questiontype.
Was not very difficult as nearly all code is copied verbatim from match questiontype.
Also this questiontype should now work correctly with item analysis and detailed responses reports.
The only modified file is question/type/renderedmatch/questiontype.php
This should solve MDL-6752 bug.
Of course I have made some tests but will appreciate feedback if some of you can test that their renderedmatch questions are correctly saved and restored.
Next step will be to upgrade this questiontype for moodle 1.8 and 1.9. Will do this during summer.
