Remove soundex module, as stated by GvR.
(Fred, I'll leave the doc changes to you, because I don't know if you want to delete libsoundex.tex or leave it in. Someone else will have to tweak PC/os2vacpp/{config.c,makefile} and PCbuild/pythoncore.dsp, both of which refer to soundex.c)

- Perform soundex comparisons on strings.
-
- Soundex is an algorithm that hashes English strings into numerical value.
- Strings that sound the same are hashed to the same value. This allows
- for non-literal string matching.
-
- From: David Wayne Williams <dwwillia@iucf.indiana.edu>
-
- Apr 29 1996 - added get_soundex method that returns the soundex of a
- string (chrish@qnx.com)
- May 2 1996 - added doc strings (chrish@qnx.com)
