Damageforwarder Fix

* switches voxel speeds in physics
* even distribution of damage to neighbouring voxel, linear from 100% at 0° to 0% at 90°

Dont be confused by the big holes that are teared now. A bullet currently has a speed of sth like 70 which, currently, equals 70 units of hp-damage. Since every voxel only has 1 Hp... you get the idea
