Improve font rendering

[piotr-bajer]

Hi guys, I often get comments from clients that on macos fonts look bolder. Can we add following style rules:

* {
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-rendering: optimizeLegibility
}

It may go at the top of elements/_html.scss file (https://github.com/xfiveco/generator-chisel/blob/13602e6389d07bc2e91177ec20c3001ae0b76ab8/generators/app/templates/styles/itcss/elements/_html.scss)

Definitely, but I think it's enough to do it on html, no need for *.

@jakub300 You are right, both properties are inherited, can be applied to html
