Nuclear mine balance

[Loken]

Nukes were alright few years ago. You only got full damage with direct hit, and it gradually dropped to 0 at the edge of the explosion effect zone.
I don't know when, how or why, but this vanilla feature was removed for mine hull damage (still in place for shield damage).
Now mines deal only max damage.

4.86 is when this was changed. More than a few years at this point.

It is the side effect of a hack that was applied to explosion damage to make torpedoes deal damage consistently to large ship models. Prior to that nobody used Novas, because they didn't work.
