First cut at adding new "fixed" Match question type, which is manually created. Works OK after limited testing.

Later there will be a new 'Random Match' which randomly selects one of the existing "Match" questions.

New modular plugin structure for quiz reports. The code for reviewing an existing attempt is now separate in review.php and now has a log entry of it's own. The overview and regrade reports are now in separate subdirectories under the "report" directory. Each has a primary "report.php" file which implements the report as a class. These existing reports are very simple, but now more complex ones can easily be written. (I am about to do one).

Added some bug-fixing code from Eloy Lafuente that fixes a quiz problem. What happens is that adding random questions used to set the timestamps of these questions to the same value. This is fine in normal operation, but it stuffs up the backup of that course, overwriting the question. When the course is restored, the missing questions cause quizzes to have lots of red notices like "Question not found". Anyhow, this patch should safely fix older installations that may have these duplicate questions lying around. THANKS ELOY!
