Merged Henry's latest changes to add support for character ranges

in cvec data type

Added support for Unicode character classes in regular expressions
We now support the following character classes:

  alnum, alpha, blank, cntrl, digit, graph, lower,
  print, punct, space, upper, xdigit

These all follow the example set by the GNU regular expression package
for Java except that "digit" only matches the ASCII '0'-'9'
characters.

Renamed tclUtf.h to tclUniData.c
