[Gameplay A24] - Drastically change artillery attacks.

Browse Source 
Artillery is not that effective in 0 A.D., partly because their damage
per second is unimpressive (especially compared to rams or war
elephants), partly because of their splash damage.
Splash damage was added in f72d820cd4 (nearly eight years ago). The
values have changed multiple times, as has the exact calculation (see
simulation/components/Attack.js). While it's quite interesting in
theory, in practice it's not that effective. @fatherbushido explained
how it works on the forums. It's important to understand the actual
splash damage depends on the distance to the centre of entities, in
contrast to ordinary attacks, which do full damage when they hit the
footprint (edge).
Splash damage has some serious problems:
- It may have no effect vs entities with footprints longer than the
splash radius, such as many (most?) structures and warships.
- The AI does not take it into account.
- It's anachronistic: exploding shells did not exist yet in 0 A.D.'s
timeframe. Missiles were rigid objections, and even the very largest
projectiles were well under a metre in diameter.

This patch therefore removes splash damage from artillery (except bolt
shooters).
Fireships and fireraisers now deal fire damage instead of a combination
of other damage types.

Basically, stone throwers are good against large unit masses and
structures only, while bolt shooters are unit killers.
Artillery and bolt towers no longer get additional projectiles from
garrisoned units.
Roman artillery does not get a larger range but keeps the increased
damage.
