Adding font-smoothing to index.css

[goncy]

Without

With

index.css

  margin: 0;
  padding: 0;
  font-family: sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
}

I'm not a fan of having the prefixed properties on the index.css but just webkit and moz support it and with a different name, but i think that there is a lot of people that doesn't know this little trick and will be a good touch for apps with a lot of content. I can make a PR.

PD: Also a question, why the App header is fixed to 150px? If you remove it it's the same height but if you remove the logo or the text you have to remove the css line to get the correct height. Can make a PR also for that.
