Add changelog auto detection in workflows please

[schneems]

1) Click "Actions" 2) Navigate to make a manual action 3) name the file something like "check_changes.yml"

Put in this config:

name: Check Changelog

on: [pull_request]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v1
    - name: Check that CHANGELOG is touched
      run: |
        cat $GITHUB_EVENT_PATH | jq .pull_request.title |  grep -i '\[\(\(changelog skip\)\|\(ci skip\)\)\]' ||  git diff remotes/origin/${{ github.base_ref }} --name-only | grep CHANGES.md

This requires that all PRs touch the changelog or have CI SKIP or CHANGELOG SKIP in the PR title. That way your changelog is already filled out when you go to release a new version instead of having to manually go back and add it.

Thank you for your feedback. But, I think this isn't necessary for this project.

@kou How do you think?

I think this isn't necessary too.

Thank you for reviewing the issue. I find this helps to make contributing faster in this scenario:

• One contributor makes a PR, all tests pass
• They go away for a few days, eventually, the maintainer comes and reviews it. They see "oh, there is no changelog entry" so they ask for one
• A few days later the contributor is able to get back to it, then they make the change.

It also reduces the errors of this scenario:

• One contributor makes a PR, all tests pass
• They go away for a few days, eventually, the maintainer comes and reviews it. They either do not notice that there is no CHANGELOG or they think they will add one manually and forget.
• Later a release is made, the changelog is missing entries.
