Pinned all dependencies

[yocontra]

👋 Hello!

We’re all trying to keep our software up to date, yet stable at the same time.

This is the first in a series of automatic PRs to help you achieve this goal. It pins all of the dependencies in your package.json, so you have complete control over the exact state of your software.

From now on you’ll receive PRs whenever one of your dependencies updates – in real time. This way you get all the benefits of up-to-date dependencies, while having them pinned at the same time. This means:

• No more surprises because some of your dependencies didn’t follow SemVer. Your software is always in a state you know about, regardless of when someone does $ npm install.
• If you have continuous integration set up for this repo, it’ll run automatically. Ideally, it will pass and you'll stay up to date with the press of a button. If the updated dependency does break your software, it won’t affect your users, because their dependencies are still pinned to the working state.
• You can immediately identify which dependency updates break your software, because each one is tested in isolation. You’ll also have a branch ready to work on, so adapting to new APIs is way faster.

Merge this PR and you’ll have up-to-date software without the headaches ✨
