Daimona Eaytoy 2dd8d27c34 Allow customizing block durations for each filter 
This is part of a project to enchance blocking in AF. With this patch,
users are allowed to specify two block durations for each filter, one
for anonymous and one for registered users. For backward compatibility,
default values are set to the global variables.
