[REQ] claimed tonnage instead of confirmed for tonnage aces

[AntEater]

That is really a no brainer, and it bothered me even with SH3.
In Sh4, as well as SH3, the "ace board" shows the tonnage the skippers sank.
these numbers were the confirmed numbers which were only found out after the war by meticulous research.
In chase of germans, it was the MFGA (German armed forces research institute) under Jürgen Rohwer in the 1960s.
In chase of the US in SH4, it was the JANAC commission which started work immidiately after the end of the war.
The tonnage of US skippers was trimmed drastically downward.
But in wartime, the claimed tonnage was much higher.
Having postwar research results in the base screen is a bit like the sports almanach from "back to the Future II".
For example, Dick O'Kane was credited by JANAC with 24 ships for just over 100.000 tons. He himself claimed 33 Ships with over 300.000 tons!
Early in the war, the figures differed even more.
It give the player a lot more sense of competition if he wouldnt be propelled to an instant number 1 with an average patrol in 1942 (and get no award to show for it!).

(Edit)
Since I have nothing better to do, I got to it myself
5 of 38 aces allready done
The SH4 list is broken down by sinking dates.
That means, the instant O'Kane or Morton sinks a ship, you the real tonnage of that one is magically displayed on the blackboard...
For ease of work and realism, I changed the updates to a date after the respective skipper returned from war patrol or the death date of that skipper.
I simply used the patrol appendix of Silent Victory as reference.
