Implement 3XDAMVDEM Logic for Arrows

[kphoenix137]

The Deadly Hunter bow contains the 3XDAMVDEM affix power which isn't present in missiles.cpp, preventing the affix from doing anything altogether. This fix adds the logic from player.cpp in a consistent way with how damage gets handled in melee combat.

This is clearly a bug, but if this bow was doing three times the total char damage it will be far too powerful, totally breaking the balance in the game. I propose another fix, to simply remove the IPL_3XDAMVDEM affix from its properties and assume that the bug is not implementing the damage, but removing the affix from the item once they decided that the extra damage should not be implemented.

The scope of DevilutionX isn't to change the balance of the game, but to fix bugs and improve the game engine

So let's assume the bug is forgetting to remove the affix.

Afaik this will cause all missiles shot by the player 3x, it should be limited to only arrows.

The MissilesData[t].mType == 0 condition should only apply to arrows so that should already be handled.
