Add support for react-icons

[NFNChris]

The popular react-icons module provides FontAwesome icons (among others) in best practice SVG format. I have put together a pull request that provides optional support for this library, which at the time of writing has almost 350k weekly downloads.

It seems listing "react-icons" as an "optionalDependency" in package.json results in an attempt to install it by default. I guess the alternative would be to simply leave it out of package.json entirely.

This is building locally for me without issue. It seems the TeamCity build failure is unrelated to the code and something to do with the build environment:

Thanks for this!

I'm wondering if it makes sense to just do a major version bump and include react-icons as a normal dependency.
