More ambient sounds

[ziomke]

What about more ambience in PB3? The ones we have in PB1 and 2 are pretty boring.

Outdoors:
- distant singing birds
- perhaps distant gunshots and explosions?
- distant vehicles (cs jeeps and other ground vehicles)
- better wind sounds (occasional louder wind gusts and snippets)
- (at night) maybe crickets and other animals?
- buzzing flies near the player
- (underground/in a cave) water dripping, maybe some rock rumble
Indoors:
- blips and beeps or something (this would play near some future advanced computer or other technology, machinery stuff)

To actually use this much, you'd need a region and a trigger at that point.

While at it, i might as well suggest using different sounds for different types of walls.
