Improve renovate config

[ZauberNerd]

Pimp our renovate config with more specific rules:

• add "untool" as package to the untool monorepo group filter
• peerDependencies should be "widened (ie: "react": "15 || 16" instead of upgrading to 16)
• devDependencies should be bumped (ie: an update from prettier@^1.0.0 to prettier@1.1.0 which would normally fall under our version range, should be updated to the new range: "prettier": "^1.1.0")
• devDependencies in the root package.json should be auto merged if they are a minor or patch upgrade

Why not restrict renovate to non-office hours any more? This might prevent some conflicts, does it not?

Automerging is not going to work: renovatebot/renovate#846

What kind of conflicts are you talking about? I initially enabled this option, to preserve our travis-ci resources, but disabled it now, because there aren't too many PRs being opened anyways (I think renovate already restricts this to max every 2 hours).
