[tz] Barnaby

OK, first pass of http://code.google.com/p/barnaby is available for download of the source. This is a C++ library with two functions: 1) List all of the timezones 2) For a given timezone name, convert UTC to that timezone It will build a DLL for you if you open the project using Visual C++. The timezone data is only version 2011i, so I will need to update it soon. Please let me know any and all feedback. Blessings!
