Three improvements:
1. $nomoodlecookie = true. I just found out about this undocumented(?) hack(?)
in lib/setup.php which is the perfect way to suppress some warnings. We
don't need a session cookie for the chatd.
2. If allow_call_time_pass_reference is Off, socket_getpeername can't work.
3. Suppress "call time pass by reference is deprecated" messages for
socket_getpeername, we don't have any choice here.
Fixed the annoying "...and the 1 Journals you had..." message when you have
no Journals at all, because I was tired of seeing it.
count(false) is 1 and not 0.
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

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
1) in all module-indpendent code the variable $quiz has been renamed to $cmoptions (it holds the options set by the course module which does not necessarily have to be a quiz, it could be a lesson for example).
2) quiz_restore_question_sessions() has the simpler name quiz_get_states
Also got rid of the quizfile.php in favour of file.php
Moved all code that is not specific to the quiz module out of locallib.php into questionlib.php.
The default questiontype class is now defined in quiz/questiontypes/questiontype.php.
See http://mantis.york.ac.uk/moodle/mod/forum/discuss.php?d=852
In a lesson's settings one can now set the current lesson to be dependent on another lesson in the same course. Then, the user can set the conditions for the dependency. Currently the conditions are time spent, grade better than X, and completed (yes/no).
