Less splash damage than there should be

[Dethdeath]

This is basically the same issue as #452 I think some splash damage was fixed since then, particularly vehicle explosions. However, for things like the decimator secondary fire mode, the splash damage is nowhere to be found. Reaver rocket pods still don't do enough splash damage either, this is most apparent when shooting at infantry. If anyone comes across more instances of low or missing splash damage, feel free to add to this.

This is what both Decimator shots look like according to the ADB:

add_property phoenix_missile_projectile damage0 80
add_property phoenix_missile_projectile damage_at_edge 0.3
add_property phoenix_missile_projectile damage_radius 1.5

It has a really small splash damage radius and will only do 24 damage at furthest from infantry targets.

The Reaver rocket projectiles look like this:

add_property reaver_rocket_projectile damage0 25
add_property reaver_rocket_projectile damage_at_edge 0.1
add_property reaver_rocket_projectile damage_radius 3

It has twice the splash damage radius as the Decimator but will only do 2 damage at furthest from infantry targets.
