Fix 2 decal issues

• Fix decals not appearing when a projectile with 0 size (blaster, crylink, hagar) hits a surface with a small angle. This fix also improves the previous fix for the same issue for hitscan weapons (1db2592b)

• Fix #2128 (closed) "Hitscan weapons create no decals when shooting almost straight down at the floor I am standing on"

• Save 3 bytes by sending the force vector slightly compressed
