Change log:
Version 1.6.13 (built with libpng-1.2.34 and zlib-1.2.3.2)
Added "-time_stamp" directive, to cause pngcrush to write
a new timestamp on the output file instead of replicating
the timestame from the input file.
Version 1.6.12 (built with libpng-1.2.34 and zlib-1.2.3.2)
Version 1.6.11 (built with libpng-1.2.33 and zlib-1.2.3.2)
