Loader should support different configs

[mdreizin]

It would be nice to have ability to use custom configs via https://github.com/webpack/loader-utils#getloaderconfig

@mdreizin hi! Sorry for delay. You can specify different configs in 0.0.26 via config option like this:

{
  module: {
    loaders: [
      {
        test: /\.svg$/,
        loader: 'svg-sprite?config=svgConfig1'
      }
    ]
  },

  svgConfig1: {
    name: 'tralala_[name]'
  }
};
