add svg-sprite-loader

[formatlos]

I've added a ?sprite resource query to be able to create a SVG sprite instead of including the whole SVG markup for every use of the icon.

Thank you very much for your contributions @formatlos! :)
Thats cool, I didn't know the sprite loader yet, but it is definitely better than the ?inline option when the same icon is used multiple times.

I'm currently on vacation but I'll merge your PRs and publish them to npm as soon as I am back home again on tuesday.

thanks for the quick merge @cyrilwanner , could you also publish a new version to npm?

Sorry for the delay, as I saw some options of the svg-sprite-loader, I wanted to add some other smaller improvements (in #13) but I didn't have time for it yesterday.
These are basically:

• Add a notice for SSR to the readme
• Also optimize svg icons used in sprites in production (removing comments etc)
• Use a runtime generator for easier usage and so we won't need the verbose <svg> and <use> elements in every usage (viewBox, id, etc is still exposed and your example will also still work):

import React from 'react';
import MyIcon from './icons/my-icon.svg?sprite';

export default () => (
  <div>
    my page..
    <MyIcon />
  </div>
);

Everything is now published as version 1.3.0 at npm 🎉

Thank you again very much for your contribution and for improving this plugin!
