freeze on exit when art finder still working

VLC sometimes freezes on exit and by debug messages it seems that happens when playlist is being deactivated while art finder is still working.

We need to wait for the art finder thread to terminate.

I am afraid the only way to terminate it asynchronously would require supporting cancellation from with the LUA interpreter. Best of luck with that...
