Make fonts nicer on Macs

Removed the `antialias` setting which tells Chrome to not use native font rendering and instead use something from the late 2010's that isn't subpixel-friendly and looks very blocky. This used to be required when OS X browsers didn't antialias by default because it made fonts look bolder than on Windows. This has since been fixed and we are advised to not use `-webkit-font-smooth`.
