Log Message:
Update cgoban-java to 2.6.11.  Notable changes include:

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

 - Icons got screwed up when you used a large font.

 - Some windows get scrambled on occasion. Hopefully fixed, hard to
say for sure if all window screwups have the same root cause, but I
know that I fixed at least one such bug.

 - Changes to auto-link-underlining code was causing crashes on
some systems.

 - Assistants still weren't able to edit MOTD, now it should be
possible.

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

 - Private tells from admins & assistants can no longer be censored.

 - Workaround for Java AWT/Swing bug that was making it take extremely
long to load large SGF files when you used Java 1.5. "Extremely" here
means, I left it running for hours, it was still not loaded...well, it
was loaded, but the display of the game map still wasn't done.

 - Guests no longer have any rank info at all, so they can be
spotted more easily.
