3D Sounds + Rewrote the explosion sound to be more optimized and to be more dynamic.

* 3D sounds! All sounds, which use playsound(), are now 3D. Meaning if you are further away from a source of noise, it will sound quieter and if the source is left of you, you'll hear it more to your left stereo speaker.
* Changed playsound() to use less code. Playsound now loops through the player list, which means you do not have to check inside closets/objects/other mobs to play sounds.
* The piano now uses 3D sounds.

* Explosions that are close to you play the usual sound.
* Explosions which are far away will play explosionfar.ogg, but with volume changed depending on the distance.
* Max cap (3, 7, 14) bombs will play explosionfar.ogg for half of the station (115 tiles).
* A small bomb's sound radius will be much less than max cap bombs, and be quieter (so you can tell the difference).
