Scale down volume of all sounds, fixes #179

so even with many loud sounds the overall volume isn't reduced by
OpenAL - apparently OpenAL scales down all sounds temporarily if the
mixed result would be too loud or sth like that.
Just sending all sounds to OpenAL with a lower volume prevents that from
happening (just set your system speaker volume a bit higher if needed).
This problem was especially noticable when shooting at metal walls with
the shotgun (each pellet produces an impact sound so it gets kinda loud)
