I desperately needed to set a custom title in the throughput module, so...

...I reworked it a bit to accept at least title=... and no-title. Copied code from the TimeSequenceMod class.
This patch doesn't do any more than accepting a custom title for the throughput module.
Maybe I add other options later, but for now this works for me.

OK, now I have to run this over a few hundred pcap-files again :-)
