Update cgoban-java to 2.6.6.

Changes from version 2.6.5 to 2.6.6 (Released 2004-10-27)

Bugs Fixed
----------

S - Fixed a server bug that would sometimes make it crash on shutdown
(luckily the crash would happen after all data needed had been written
out, so it was harmless but annoying.)

C13 - Got the "change whose move" control working again.

C13 - Added a tool tip for the "no chats" button.

C13 - Fixed rating system issue. Broke rating system in the
process. Ranks are now much too stable. Sorry, will be fixed when possible.

S - When the teacher leaves, the chat mode of the game will now revert
to normal.

S - Added tests to ensure that game state only changes when game mutex
is held (server crash looks like it was caused by a game changing
state when mutex wasn't held).

C13 - No longer tells you how to upgrade an applet when you are using a
non-applet client.

S - Fixed a bug that caused several crashes recently (caused a loop in
the linked list of clients needing data written).

Features Added
--------------

S - Added throttling of comments sent to teachers in moderated mode.

S,C13 - You can now undo in tournaments, but only when you are marking
stones dead.
