Changes for Games::Sudoku::Pdf

v0.02 

	Omitted the time zone offset minutes, together with the trailing apostrophe.
	This way we stay conformant with iso and adobe standards and PDF::API2 before v2.044 won't croak.
	Global 'size' and 'justify' replaced by 'column_props', which has better compatibility across PDF::Table versions.
	Changed the shebang in exe script from '/usr/bin/env perl' to just 'perl'. (Slaven Rezic)
	Renamed sudoku2pdf.pl to sudoku2pdf to make it look command-like.
	Fixed parameter name in example.pl.

v0.01 

	Initial Release.
