Decor Sounds 0.7.8 beta

WoW catalogue previews now silence other Decor Sounds playback, including house backgrounds, room sounds and sound zones. Normal playback returns when the preview ends after eight seconds, Stop is clicked, the browser closes, or playback fails. Changing search/category also stops the preview and restores playback. Leaving the world clears the temporary preview. Game audio settings remain unchanged. Background loops restart when restored; this is not a seek/pause facility.

Install by merging DecorSounds into Interface/AddOns with WoW closed. Preserve DecorSoundsLibrary and Sounds/User. Studio remains 0.7.8.
