* chore: update dependency prettier to v1.13.0

* run prettier

This PR replaces the existing `pinVersions`, `upgradeInRange` and `versionStrategy` settings with a single one: `rangeStrategy`.

Previously:
 - `pinVersions` could be `true` or `false`, but defaulted to `null`, which meant that Renovate would decide. `true` meant that Renovate would replace existing ranges like `^1.0.0` with an exact/pinned version such as `1.2.0`.
 - `upgradeInRange` could be true or false, default to false. If `true`, it would mean Renovate would replace an existing range like `^1.0.0` with something like `^1.2.0`
 - `versionStrategy` could be `replace` or `widen` and was mainly used for `peerDependencies` to widen existing ranges, e.g. from `^1.0.0` to `^1.0.0 || ^2.0.0`

It was possible to set conflicting settings, e.g. configuring `pinVersions=true` and `upgradeInRange=true`.

Now, we combine them into a single setting: `rangeStrategy`:
 - `auto` = Renovate decides (this will be done on a manager-by-manager basis)
 - `pin` = convert ranges to exact versions
 - `bump` = same as `upgradeInRange` previously, e.g. bump the range even if the new version satisifies the existing range
 - `replace` = Same as pinVersions === false && upgradeInRange === false, i.e. only replace the range if the new version falls outside it
 - `widen` = Same as previous versionStrategy==='widen'

- It is changed from https://renovateapp.com/docs/configuration-reference/configuration-options to https://renovatebot.com/docs/configuration-options/

Closes #1929 

This PR deprecates the use of `packageFiles` and migrates it to `includePaths` and `packageRules`.

Closes #1887

Renovate now comes with a variety of package managers supported, each with their own filename pattern(s). These patterns are now exposed for user configuration through the new `fileMatch` list/array configuration option, which has been added to each manager (npm, bazel, docker-compose, etc). `fileMatch` is defined as a mergeable list, meaning that users can add to the default pattern to extend the files being detected.

Closes #799

Rules for dep types (e.g. dependencies, devDependencies, peerDependencies, optionalDependencies) should now be done with `packageRules` and the `depTypeList` selector
