Ready for release
Silence a failure from Perl::Critic about return(undef)
Version bump
Switch to Git::Tag
 Several changes by Brendan Byrd:

 - Complete support for large numbers in all directions, and
   for large floats.
 - Ability to specify a different negative sign or radix point,
   if - or . will be used as a digit.
 - Short-circuiting to the more efficient sprintf/oct functions
   for bin/hex/oct conversions.
 - Ditching Horner<92>s algorithm in favor of exponent-based one that
   is more accurate for fractionals.
 - Module will die if an invalid character is found.
 - Changed tests to use new_ok if possible.
 - Added Unicode tests to make sure they continue to work.
