Changed love.graphics.newImage's optional second argument to be a table of flags. Current flags are 'mipmaps' and 'srgb'.

If mipmaps are enabled on image creation, the image will use the default mipmap filter (now 'nearest' by default.) Image:setMipmapFilter will error if the image was not created with mipmaps enabled.
