Update to 2.1.0:

Version 2.1.0 (oct.29th 2014)
  Bugs fixed:
    * The switch -sysinfo worked only in Windows - in Linux (?also in Mac?) the
        clipboard is deleted on exit
    * extensive work in the SGF-parser, "\" and "]" are \ 
handled correct IN THE
        PARSER (not yet in the display)
  Further:
    * SGF FF[3] files (AddWhite, SiZe, DaTe, CiRcle, ...) are now processed and
        displayed!!
    * Files from a defect version of Hibiscus 2.1 (LB[yy:0]...) are now displayed
    * Many defect SGF files get now a suitable error message; a stacktrace is
        only shown for debugging (internal switch "DEBUG2"). Normal \ 
file errors
        shouldn't give a stack trace. (If you have a defect sgf file, which
        doesn't get an sppropriate error message - let me know!)
    * Grinder has now an extra log file for SGF file errors: sgf-log.txt
