Update p5-common-sense from version 3.00 to version 3.1.

Upstream changes:
3.1  Sat Apr  3 04:56:36 CEST 2010
        - removed "parenthesis" warning:
             sysread $fh, my $buf, -s $fh; # ok
             sysread $fh, my $buf, $size;  # warning
          Made no sense to me, especially as $size is in scope.
	- no longer hardcode warning/struct bits, calculate them at
          installation time, for when I will no longer be alive etc.
	- tweaked documentation.
