stronk7 25ef0370d5 Improved automatic relinking in backup and restore. Credits go to skodak.
Complete refactoring of the system that was really awful (my fault!).
Now everything is in its place and working like a charm, making things really
easier to be implemented and amplied. Bug 3678
(http://moodle.org/bugs/bug.php?op=show&bugid=3678)
(http://moodle.org/mod/forum/discuss.php?d=26530)

Note: Everything is merged from stable but the quiz module because it has
other changes not merged for now. I've skyped a message to Gustav about it.
