note 14245 added to function.soundex.php

The comment from fishy is wrong about the exact algorythm: Capitalization of letters are ignored in this algorithm. 1) C should be made aqual to the initial capital letter as indicated. 2) Vowels and H are significant despite they do not generate a numeric code: they are still used to separate sequences of consonant letters. All sequences of vowels or H are equivalent to a single separator 3/4) Before converting the remaining consonnant letters, one should eliminate multiple occurences of the consonnant letters in the same conversion group, provided that they are not separated by a vowel or H: "Lissajous" results in L222 because the first "2" is generated for "ss", the second "2" is generated for "j" because vowels separate "ss" and "j". http://www.php.net/manual/en/function.soundex.php
