Even more complicated redirect scheme

Browse source 
This:

    ?_filter_column_1=name&_filter_op_1=contains&_filter_value_1=hello
    &_filter_column_2=age&_filter_op_2=gte&_filter_value_2=12

Now redirects to this:

    ?name__contains=hello&age__gte=12

This is needed for the filter editing interface, refs #86
