Expose 8× MSAA antialiasing in the graphics options menu
High-end/mid-range GPUs from 2016 and later can easily handle 8× MSAA in Xonotic, so the option should be exposed in the graphics options menu for increased visual quality. Right now, you can only select Disabled, 2× and 4× MSAA.
16× MSAA shouldn't be exposed as it will probably break things, since there's no such thing as 16× MSAA. Instead, graphics drivers implement it as a mixture of 2× SSAA and 8× MSAA.
In the meantime, entering vid_samples 8; vid_restart
in the console works.
