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. Merged from MOODLE_15_STABLE
