Feature #10084: Add Unicode String Normalization to String class

----------------------------------------
Unicode string normalization is a frequent operation when comparing or normalizing strings.

This should be available directly on the String class.

The proposed syntax is:

   'string'.normalize       # normalize 'string' according to NFC (most frequent on the Web)
   'string'.normalize :nfc  # normalize 'string' according to NFC; :nfd, :nfkc, :nfkd also usable
   'string'.nfc             # shorter variant, but maybe too many methods

There are several "unofficial" but convenient normalization variants that could be offered, e.g.:
                           
   'string'.normalize :mac  # use MacIntosh file system normalization variant

Implementations are already available in pure Ruby (easy for other Ruby implementations; e.g. eprun: https://github.com/duerst/eprun) and in C (unf,���, http://bibwild.wordpress.com/2013/11/19/benchmarking-ruby-unicode-normalization-alternatives/)
