No "real" capture of HTTP:BL response

Unfortunately the RBL operator returns the originally IP on match, but not the "real" response. This means, that this operator only could be used on a boolean base like "If there is a DNS response, then match".

IMHO being able to filter requests based on a score would be much better and more feasible, so I changed the code like mentioned below.

rbl.cc before 236

    if (rule && t && rule->hasCaptureAction()) {
        char *respBl;
        int first, second, third, fourth;

        respBl = inet_ntoa(sin.sin_addr);

        if (sscanf(respBl, "%d.%d.%d.%d", &first, &second, &third, &fourth) != 4) {
            ms_dbg_a(t, 4, "RBL lookup of " + ipStr + " failed: bad response");
            //return false;
        }
        else {
            t->m_collections.m_tx_collection->storeOrUpdateFirst(
            "1", std::string(respBl));

            t->m_collections.m_tx_collection->storeOrUpdateFirst(
            "2", std::to_string(fourth));
        }

        furtherInfo(&sin, ipStr, t, m_provider);
    }

rbl.cc before 126

        trans->m_collections.m_tx_collection->storeOrUpdateFirst(
        "2", std::to_string(score));

        trans->m_collections.m_tx_collection->storeOrUpdateFirst(
        "3", std::to_string(type));
        trans->m_collections.m_tx_collection->storeOrUpdateFirst(
        "4", std::to_string(days));

Start by reading src/operators/rbl.cc at the linked regions and compare current behavior with the historical snippets. Trace how the RBL response and transaction captures are represented; done means the operator exposes the real response data needed for score-based filtering rather than only the original IP.
