MDL-7962 chat seems to be completely broken in head (fixed wrong JS)
* reworked chat themes support
MDL-8338 Cron does not need cookies
MDL-8339 forum cron capabilities problems
* minor deprecated function current_encoding() cleanup
Some users reported that mod/chat was silently dropping some messages. The
user's browser may not be able to keep up with the rate at which he submits
chat messages. This update keeps things sane.

+ we are now more conservative in the fields it asks from the db
+ also more conservative with upates to chat_users
+ messages are now added via POST requests instead of GET
It's not well tested yet - I'm hoping to do some testing on moodle.org
with some real people and get this refined enough for the Beta release
later today.
