Adds the "BOOM, headshot!" sound from FPSDoug into the game.

Requires:

1. SuperBLT (obviously)
2. BeardLib (obviously)
3. ACHH (Advanced crossharis, hitmarkers and hitsounds)

To install, drag the folder to your mods/saves/ACH Addons/Hitsounds folder. If you do not have such a folder, you can make one.

Included in the zip are 2 audio variants, one with just "BOOM!", and another one that has the full "BOOM, headshot!" sound effect.
