Added flag for perfdata summary 

For the visualization the sum of the blocked IPs is more interesting to me than the individual jails. So I added a --summary flag which adds the performance data for sum jails and sum current banned ip addresses. It is also possible to combine the --summary with the current --perfdata to get both.
