ANN: pyparsing 1.0.4 released

[Paul McGuire]

pyparsing version 1.0.4 is available at
http://sourceforge.net/projects/pyparsing/.

Version 1.0.4 contains:
- more performance improvements (another 30-40% reduction)
- positional token expressions (StringStart, StringEnd, LineStart, LineEnd)
- commaDelimitedList convenience built-in
- more example scripts (HTTP server log parser, comma separated list parser)
- fixed typo in setup.py

- minor API change: delimitedList no longer groups the results, this is now
the responsibility of the caller (using Group(delimitedList(expr)))
