Fixed WAF install paths issue on Windows. * Reorganized the waf_paths.py WAF tool so that install paths are correctly set on Windows. * Added ordereddict.py for use by the waf_paths.py WAF tool on python versions less than 2.7. * Renamed the waf script to waf.py so that Windows users get the benefits of the .py file extension. * Fixed a bug where the FifePath entry in parpg.cfg was not getting set to the default python site-package path. * Fixed a bug in the Windows parpg.bat launcher where quotation marks (") were screwing up the PYTHONPATH variable.
