Missing polyfill functions

I'm asking this because this plugin is in use @ **Webpack 3** via [node-libs-browser](https://github.com/webpack/node-libs-browser).

It would be nice to include [a bunch of functions handlers](https://github.com/paulmillr/console-polyfill/blob/master/index.js) for this, such as `console.table`, or a generic handler that can stub any function call so that it won't result in an error (crucial for legacy browsers).

Otherwise this polyfill is starting to be a bit outdated.
