Airship weapons

Airship weapons is a category of boardable entities that encompasses the guns mounted on large airships. These include:
 * Machine guns, designed for sustained rates of fire over per-bullet damage.
 * Cannons, which fire a single, large projectile at the target that deals large amounts of damage. Naturally, it has a low rate of fire and requires a degree of skill in use.
 * Flame cannons, close-combat weapons bathing the enemy in a stream of flames.
 * Automatic machine guns, which are the standard variant with the added bonus of autonomously attacking targets designated by the pilots.
 * Turrets, which are another type of autonomous weapon system that fires missiles.
