[WIP] Historical Guns Specs

[gap]

more discrepancies LOL

uboatarchive lists some typical specifications pertaining to U-boat armaments. Practical rates of fire reported for deck guns and 2 cm FlaKs are in line with our settings, but not the ones relative to 3.7cm guns:

SK C/30U: 12 rpm (slower than the 10.5cm deck gun!) vs. 30-40 rpm reported by other sources;
M42 U: 40 rpm vs. 150

Moreover, it is specified an M42 clip size of 8 rounds which, even considering the trick of loading one or two loose shells in advance, doesn't add up with the 5 rounds reported by most other sources

Changing of argument, the U Bootskunde für U Boote Bauart VII C reports in the ammunition section (p. 56):

Total amount of ammunition that can be carried:
8.8 cm munitions: 205 rounds HE shell C/35
MG C/30 munitions: 1500 rounds

I had previously set 220 rounds for the 8.8 cm gun, and 1,100 rounds per muzzle for 2cm FlaK's; I will revise our settings accordingly. However it is to note that the above document is relative the early armament layout, with a single 20mm C/30-C/38 FlaK gun. Other sources report a maximum total loadout of 4,380 2cm rounds per boat. It means a proportionally reduced outfit for later 2cm FlaK models due to the use of multiple mountings/guns on the same boat.
