Dongsheng Cai f97b86e841 MDL-72991 Course: Partial course cache rebuild
When updating/deleting a section/module, the system now only
invalidate of the element (section/module), not the whole course cache
Also, the system now only recalculate the cache for element (section/module)
if necessary, not the whole course cache

Move module/section purging to course_modinfo:
  + course_modinfo::purge_course_section_cache_by_id was created to purge section by id
  + course_modinfo::purge_course_section_cache_by_number was created to purge section by number
  + course_modinfo::purge_course_module_cache was created to purge module

Official Chat Module for Moodle
------------------------------

The chat module now supports a backend daemon for
more efficiency.

It's still buggy and being worked on, but if you
want to test it and help out here are some quick
instructions:

1) Admin -> Config -> Modules -> Chat -> Settings

2) Set the method to "sockets" and set up the ports etc

3) Start the server like this (from the Unix command line):

   cd moodle/mod/chat
   php chatd.php --start &

4) Go to a chat room in Moodle and open it as normal.

KNOWN PROBLEMS

 - User list is not always working
 - Some browsers (eg Safari) cause lines to be repeated
   by 10 - 20 times
 - Occasionally "Document was empty" messages

Help solving these very welcome!
