(react-native-svgkit) SVG support for macOS

If you have a `.svg` file or URL that you want to render, check out my new library.

https://github.com/alloc/react-native-svgkit

I haven't published it to NPM yet, so you'll need to install from Github like so:

```sh
npm install alloc/react-native-svgkit#0.1.0
```

For more info, see the README.
