add to awesome list

[erwanp]

The list I'm submitting complies with these requirements:

• [x] Has been around for at least 30 days - That means 30 days from either the first real commit or when it was open-sourced. Whatever is most recent. - It's the result of hard work and the best I could possibly produce.
• [x] Non-generated Markdown file in a GitHub repo.
• [x] Includes a succinct description of the project/theme at the top of the readme. (Example)
• [x] The repo should have awesome-list & awesome as GitHub topics. I encourage you to add more relevant topics.
• [x] Not a duplicate.
• [x] Only has awesome items. Awesome lists are curations of the best, not everything.
• [ ] Includes a project logo/illustration whenever possible. - Either fullwidth or placed at the top-right of the readme. (Example) - The image should link to the project website or any relevant website. - The image should be high-DPI. Set it to maximum half the width of the original image.
• [x] Entries have a description, unless the title is descriptive enough by itself. It rarely is though.
• [x] Includes the Awesome badge. - Should be placed on the right side of the readme heading. - Should link back to this list.
• [x] Has a Table of Contents section. - Should be named Contents, not Table of Contents. - Should be the first section in the list. - Should only have one level of sub-lists, preferably none.
• [x] Has an appropriate license. - That means something like CC0, not a code licence like MIT, BSD, Apache, etc. - WTFPL and Unlicense are not acceptable licenses. - If you use a license badge, it should be SVG, not PNG.
• [x] Has contribution guidelines. - The file should be named contributing.md. Casing is up to you.
• [ ] Has consistent formatting and proper spelling/grammar. - The link and description are separated by a dash. - Example: - AVA - JavaScript test runner. - The description starts with an uppercase character and ends with a period. - Drop all the A / An prefixes in the descriptions. - Consistent and correct naming. For example, Node.js, not NodeJS or node.js.
• [x] Doesn't include a Travis badge. - You can still use Travis for list linting, but the badge has no value in the readme.
