[COMBAT SURF] Demos in surf

[Byte]

Obviously its nice to have but isn't crucial (compared to JB). Also we need permission from the server provider, we can't store huge amounts of files on disk forever. If this get implemented, demos would only last for (ie) 1 day-3days, enough time for people to request demos when needed which they may need to reupload for people to review. There is also the issue that we lose 1 player slot to GOTV but thats not too huge, could just get another slot.

Now if people ask for this on all servers then :p
