Use node for import resolving

[amannn]

The current resolver config needs a webpack config file which might not be available in every project. The only feature that we use from webpack is to provide src as an additional module directory.

We could achieve this by using node as well:

  "import/resolver": {
      "node": {
        "paths": [
          "node_modules",
          "src"
        ]
      }
    }

That would work in projects without webpack as well.
