Version 0.8.19 - 8 January 2011
* Add support for Python 2.7
* Fixed SF Bug [ 2209631 ]:
New pcmodules.py module, modulePath code causes import error

pychecker does not allow lambda with setattr and const
* Fixed SF Bug [ 1564614 ]:
pychecker -q on 64-bit ignores the platform-specific stdlib
* Fixed SF Bug [ 1563572 ]:
order of checking files affects errors reported
PyChecker was only checking one of each set of modules with the same

couldn't find real module does not respect blacklist
