Undocumented config option "Logs Directory"

[H4mmerstein]

I was looking at the code to find out how to save the backup log files in the BattlEye directory rather than in the installation directory of pyBEscanner. And what I found was an undocumented configuration option to set the log directory: "Logs Directory".
You should definitively add this helpful config option to the README and to the example config files.
