Subject: * 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
