- Fixed bug #52981 (Unicode casing table was out-of-date).

Updated with UnicodeData-6.0.0d7.txt and included the
  source of the generator program with the distribution.
#The replaced tables, generated circa 2002, seem to reflect
#Unicode 3.2. I was unable to generate the same property
#offsets with Unicode 3.2 data, but all the tests I made
#indicate php_unicode_is_prop() is returning the correct
#values. The replaced file merely says it used a "modified
#version" of ucgendat, which is not very helpful. The results
#I got were not significantly different, only slightly higher
#offsets at two properties, which were carried over to the
#subsequent properties.
#I was, however, able to replicate precisely the casing table.
#The extent of the "modifications" besides omitting most of
#the tables, a slightly different layout and the casing table
#offsets having been multiplied by 3 is unclear.
#The test suite showed no regressions; however, it's very poor
#in testing the modified portion of the extension.
