count needs to be incremented one to adjust for the UTF-16 encoding of
strings that we use.

Still needs work because the word-break tests fail.

STRING-CAPITALIZE.  Not sure about the appropriate interface, though.

code/string.lisp:
o Add Unicode word break algorithm.  Based on Scheme code by William
  Clinger.  Used with permission.
o Update STRING-CAPITALIZE to take another keyword arg to indicate if
  we should use the Unicode word break algorithm.  Default is not to
  use the Unicode algorithm.

compiler/fndb.lisp:
o Update defknown for string-capitalize.

i18n/tests/WordBreakTest.txt:
o New test file for the word break algorithm

i18n/tests/word-break-test.lisp:
o New file to run the word break test.
