A few bugs in SVN

Ohhh, you don't have a sound card? Then run "vdrift -nosound"

I'm going to remove the changes to the constructor you made, because they'll let you get around the checking and load things without successfully initializing first, which, as you found, is bad. By the way, the copy constructor and operator= members you wrote are not needed because the defaults will work fine and will automatically update whenever the class members change....

Did you get an "Error opening audio device" or "Sound interface did not create...etc" when you started the game? If so, I can make it just disable sound automatically when that happens.
