new Abalone game engine.

[Douglas Zander <dzander@solaria.sol.net>]

Hey all you Abalone players, I fixed the Abalone game engine.  The thing
is that it might be a little confusing at first.  This is what I did:
* effective immediately, all current Abalone games that were being played
  have been switched to '-short' option, meaning that you are only allowed
  to move up to 3 (and no more) marbles at a time.  Also, all new Abalone
  games will have this option as a default unless the '-long' option is
  included in the challenge command.
* IF you are currently playing an old Abalone game that you still wish to be
  allowed to move 4 or more marbles at a time, then please use the "force"
  command to force the game to switch back to how it was:

  Abalone Force 1234 Yourid YourPassWord Long

  use the actual board number of the game you wish to force and use the
  word "long" without a hyphen.  Please only use this command only if *all*
  players agree to the change in the option(s).

  The help file is updated with the new options and the new "Force" command.
  Please feel free to ask me questions privately through email.
