Update dependencies

Based on #45, we update the dependencies to the most recent version.
Some modules, however, can not be updated to the most recent version because there was a breaking change:

## `buffer`

The current `buffer` implementation uses feross/buffer@4.x because feross/buffer@5.x relies on [typed arrays](feross/buffer@5daca86#commitcomment-19698936).
This will be dropped as soon as IE9 is not a typical browser target anymore.

## `punycode`

The current `punycode` implementation uses bestiejs/punycode.js@1.x because bestiejs/punycode.js@2.x requires modern JS engines that understand `const` and `let`.
It will be removed someday since it has already been [deprecated from the node API](https://nodejs.org/api/punycode.html).

## `crypto`

We locked `crypto-browserify` at `3.3.0` because `3.4.x` introduced a breaking change by requiring JSON files. We will not upgrade this module
for webpack 1 anymore since it will introduce a breaking change for all users that don't have the [json-loader](https://github.com/webpack/json-loader) configured.
You can, however, use a newer crypto-browserify version by configuring a [`resolve.alias`](http://webpack.github.io/docs/configuration.html#resolve-alias) and using the json-loader.
