Unicode::Normalize 0.15 update

Hello.

Unicode::Normalize 0.15 is uploaded on CPAN.

Or it's also available from here.
http://homepage1.nifty.com/nomenclator/perl/Unicode-Normalize-0.15.tar.gz

new doc
http://homepage1.nifty.com/nomenclator/perl/Unicode-Normalize.html

New feature:

  - Quick check (Annex 8, UAX #15) is implemented.
  - More documentation.

E.g., if $string should be in NFC in a high probability,
saying

   $NFC_string = checkNFC($string) ? $string : NFC($string);

may be more (a bit) sufficient than simply saying

   $NFC_string = NFC($string);

enjoy.
