Weapon damage balancing for projectiles

[qwc]

(Teracon 2019 playtest)

So when we played the only weapon which did some fair amount of damage was the fireball. All other weapons just did not deal any reasonable damage.

So @skaldarnar made some delta configuration files for the weapon damage and the game got quite a bit more interesting where you were able to really kill other players.

@skaldarnar please put your deltas for the weapon configurations up in a PR for discussion (probably in the LightAndShadowResources AFAIR) and link it here.
