[mod] increase SUSPICIOUS_IP_WINDOW from one day to 30 days 

In my tests I see bots rotating IPs (with endless IP lists).  If such a bot has
100 IPs and has three attempts (SUSPICIOUS_IP_MAX = 3) then it can successfully
send up to 300 requests in one day while rotating the IP.  To block the bots for
a longer period of time the SUSPICIOUS_IP_WINDOW, as the time period in which an
IP is observed, must be increased.

For normal WEB-browsers this is no problem, because the SUSPICIOUS_IP_WINDOW is
deleted as soon as the CSS with the token is loaded.

SUSPICIOUS_IP_WINDOW = 3600 * 24 * 30
  Time (sec) before sliding window for one suspicious IP expires.

SUSPICIOUS_IP_MAX = 3
  Maximum requests from one suspicious IP in the :py:obj:`SUSPICIOUS_IP_WINDOW`."""
