Release new version

[birtles]

@johnjbarton Would it be possible to release a new version?

In particular it would be good to ship #114 and #116 since they seem to be tripping people up.

Note, however, that it is a breaking change since when we bumped standard-version to 8.0.1 in #117 I had to bump the minimum Node version to version 10.

@birtles Let's set this repo to use semantic-release. We've had great luck with it on other karma repos.

This involves a PR to add the modules and connect them to build. It involves adopting a format (which is linted) for commit messages that the release tool understands. (It may involve some admin I need to do). Then your merges will automatically release.

• Copy release.config.js
• Add devDependencies to the package.json:

"@semantic-release/changelog": "5.0.0",
"@semantic-release/git": "9.0.0",
"@semantic-release/npm": "7.0.4",
"husky": "4.2.3",

• Add the husky (linter) config to package.json:

  "husky": {
    "hooks": {
      "commit-msg": "commitlint -E HUSKY_GIT_PARAMS"
    }
  },

• Edit the travis.yml to add the action.

If you send the PR for me to review we can get it set up.
