burn.ogg can not be loaded (is missing?)

[stefanct]

if i jump into the lava in the 3rd demo a message appears telling me that /burn.ogg can not be loaded. if need be i can supply the full path.

the same happens in the 5th demo (lava rooms) and if a bot falls into the lava (AFAICS).

Hmm, looks like we are missing burn.ogg. If we find one with appropriate licensing (the one in sauerbraten isn't free enough last I checked) we can add it.
