fix newline split in generateDictionnaryPayloads

Hello Paul, 

I found the solution about the issue #2. The _split('\n')_ does not match the Windows newlines when reading the password file and causes that the JSON payload not be generated properly. I've changed to _split(/\r?\n/)_ and it works fine :).

Regards.
