bijx 006f1690a5 Warship veterancy (#4433)
## Description:

Warship veterancy! This is an idea inspired by the unit veterancy
feature of games like C&C: Red Alert 2 in which unit eliminations
increases the level of individual units. I've been trying to build this
mechanic for months with different ideas, and I finally landed on this
being one of the more balanced implementation.

Warships can earn up to three levels, represented by the gold bar
insignia in the bottom right of their warship sprite.

A veterancy bar grants 20% health from the base amount, and a 20%
increase in shell damage applied _after_ the random damage roll. For
example, a level 3 warship will apply a 60% damage boost on top of the
random shell damage value (something between 200-325. If the random
value is 250, the final damage output will be `250 * 1.60 = 400`.

There are three ways to achieve a veteran level:

1. **Eliminate another warship:** any time a warship neutralizes another
warship, it immediately get's a veterancy increase.

2. **Eliminate transport boats:** Destroying 10 transport boats will
level a warship to the next veterancy bar.

3. **Steal trade ships:** If the warship captures 25 trade ships, it
will earn a veterancy bar.
