[UI improvement] Damage per weapon stats

Dearly beloved,

While further exploring the joys of gratuitous battle statistics (see thread: Selection of ships in Battle Statistics), I’ve noticed another bit of missing functionality I’d love to see patched in. The tab “damage per weapon” provides, for some user-definable set of weapons, the percentages of missed / absorbed / hull-breaching shots. What I would like to be able to do is compare how one weapon fared in relation to another, in terms of total damage inflicted. While it’s possible to select individual weapons, there’s no way to compare one to another or to tell if that weapon caused much havoc in the first place, because we only see the percentages without knowing the absolute quantities to which these percentages apply.
