Subject: [ruby-core:24965] [Feature #1889] Teach Onigurma Unicode 5.0 Character Properties

Issue #1889 has been updated by Yui NARUSE.

Ruby 1.9's implementation is in onigenc_unicode_is_code_ctype in unicode.c and related routines.
Core routine is onig_is_in_code_range in regcomp.c. (this will be fast when CPUs and compilers is enough clever to work parallel)

It seems nice.
If the script which generates a list from UnicodeData.txt runs with miniruby or Ruby 1.8 (baseruby),
we can merge it.
