Update cgoban-java to 2.6.7.  Changes include:

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

C13 - Got audio test working again.

C13 - Fixed a bug that would let non-subscribers see KGS Plus games.

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

C13 - Changed escaper system. Chronic escapers now effectively resign
every time that they escape.

C13 - KGS Plus lectures now marked with a "+" instead of a "!".

S - When you are watching a lecture or replay, you will not get the
"You have been idle a long time" warning.

C13 - Added a confirmation dialog for admins when they enter a private
game. From time to time admins have accidentally entered a private
game, not intending to intrude; this will still let them in, but make
sure they don't do it by accident.

W - Made it possible to order KGS Plus as a gift for an account that
you don't have the password of.

S,C13 - Can now record KGS Plus lectures and play them back later.
