Epic Artillery Sounds

(Please note: This is a quick and dirty port to 0.18. As soon as the original is ported to 0.18, this will be removed.)

Description

• Changes the vanilla artillery sound to a far more powerful, resonant one. Bring the thunder to Factorio.
• Sound borrowed (then edited) from World of Tanks
