Sokoban YASC 1.654 has been published

Brian Damgaard has published a new version of his great and widely used Sokoban YASC program.

The release notes for this new version:

• Improved the level normalization tool a little. A very few levels could be further reduced by running the level normalization twice.
  This is not necessary anymore. A small run-length encoded level 
  Example:
  The level   5#|#3-#|#*@-#|#*$-#|#-.-#|#*--#|#--##|#*-#|#*-#|#--#|4#
  was reduced to
  -4#|-#--#|-#@-#|##$-#|#-.-#|#*--#|#--##|4# in the first round,
  and then to 4#|#--#|#@-#|#$-#|#.-#|#--#|4# in the second round. 
   Thanks to Anian Wu for reporting this issue.
• Minor changes.
