Docker's build process doesn't allow you to ADD or COPY files from outside the directory tree. e.g. `ADD ../package.json .` is forbidden. The only option I can see is to move it and `hooks` back into the project root.

Adds a Dockerfile for building with Docker Hub

fix: return non-zero exit code if any errors

fix: allow rebaseStalePrs=false to take priority over repo settings

Adds support for npm-shrinkwrap.json files.

Closes #67

This reverts commit 97ea483f.

This reverts commit 9b44e34f.

Upgrade ranges to latest version even if latest version satisfies existing range.

| name    | value   |
| ------- | ------- |
| type    | boolean |
| default | false   |

By default, Renovate assumes that if you are using ranges then it's because you want them to be wide/open. As such, Renovate won't deliberately "narrow" the range by increasing the semver value inside.

For example, if your `package.json` specifies a value for `left-pad` of `^1.0.0` and the latest version on npmjs is `1.2.0`, then Renovate won't change anything. If instead you'd prefer to be updated to `^1.2.0` in cases like this, then set `upgradeInRange` to `true` in your Renovate config.

This feature supports simple caret (`^`) and tilde (`~`) ranges only, like `^1.0.0` and `~1.0.0`. It is not compatible with `pinVersions=true`.

Closes #1607

Adds “renovate-config-validator” as a new bin entry to package.json. Can be run without arguments and will check renovate.json, .renovaterc, .renovaterc.json and package.json. Returns non-zero exit code with a description if there are errors.

If the existing version was pinned, or if pinVersions=true, then Renovate will use pinned versions for all the new values.
