Patch for Python port

[Miquel 'Fire' Burns]

BTW, fixed the PHP version (Just need someone to version bump it in SVN, as I don't know how to do it in command line, as I don't have TSVN installed).

Ignore the var_dump lines, didn't save the file before commiting: http://passwordmaker.svn.sourceforge.net/viewvc/passwordmaker/trunk/php/passwordmaker_class.php?r1=429&r2=487&view=patch

Note: Might want to test a few more characters in your tests, as I found an issue in which the 20th character was correct but the 21st was wrong. Add a test for 22 characters.
