Real submarines damage system

This is about the placement of the submarines' damage boxes, which are not at all correct in the vanilla game, and probably also not in supermods. I have modified them with historical technical plans, in order to put each elements to its real and proper place. Already done :  VIIB VIIC IXB IXC and XXI. To do :  II, IXD2  and VIIC 41.

Vanilla boxes :



Corrected boxes :



Moreover, I've corrected the damage_3.cfg file for an error about the damage on the type XXI batteries.
