improvements so far:
sounds will play until the player is out of the area and stop then
bird sounds depend on a random number generator when the preconditions are met
bird sounds are randomly played in different pitches for more variation
fireplaces are detected correctly and the sound effect may only play if they are burning
2 environment sound effects may play at once
fix for issue #8 is fixed now and all the comments in the sound file are disabled
Merge branch 'code_sound'
