* Start sending "ImageNotFound" packet back to the client if we can't find an image
* This might stop some client's constant requests for unfound textures, which is a candidate for the memory leak * If a texture is not found then the "Image not found" texture will now be displayed clientside * If it works, this should resolve mantis 676 * Non texture image requests do not receive this packet yet * This will require a prebuild
