Add change log file.

[skywinder]

Hi, as I can see, you are carefully fill tags and labels for issues in your repo.

For such cases I create a github_changelog_generator, that generate change log file based on tags, issues and merged pull requests from :octocat: Issue Tracker.

This PR add change log file to your repo (generated by this script). You can check, how it is look like here: Change Log

Some essential features, that has this script:

• it exclude not-related to changelog issues (any issue, that has label question duplicate invalid wontfix )
• Distinguish issues according labels:
  • Merged pull requests (all merged pull-requests)
  • Bug fixes (by label bug in issue)
  • Enhancements (by label enhancement in issue)
  • Issues (closed issues w/o any labels)
• Generate neat Change Log file according basic change log guidelines.

You can easily update this file in future by simply run script: github_changelog_generator moneypenny/soma-chrome in your repo folder and it make your Change Log file up-to-date again!

Hope you find this commit as useful. :wink:

P.S. I know that you already has CHANGELOG.md file but give this script a chance and compare it with yours change log. Hope, you will love it! :blush:
