Match current standards for awesome-lists as defined by @sindresorhus

[RichardLitt]

@sindresorhus has changed the standards for an awesome-list, and this list needs to be changed to match. See sindresorhus/awesome#926 for more.

Criteria

• 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.
• Non-generated Markdown file in a GitHub repo.
• The repo should have the following GitHub topics set: awesome-list, awesome, list. I encourage you to add more relevant topics.
• Not a duplicate.
• Includes a succinct description of the project/theme at the top of the readme. (Example)
• Only has awesome items. Awesome lists are curations of the best, not everything.
• Includes a project logo/illustration whenever possible.
  • 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.
• Entries have a description, unless the title is descriptive enough by itself. It rarely is though.
• Has the Awesome badge on the right side of the list heading,
• Has a Table of Contents section.
  • Should be named Contents, not Table of Contents.
  • Should be the first section in the list.
• Has an appropriate license.
  • That means something like CC0, not a code licence like MIT, BSD, Apache, etc.
  • If you use a license badge, it should be SVG, not PNG.
• Has contribution guidelines.
  • The file should be named contributing.md. Casing is up to you.
• Has consistent formatting and proper spelling/grammar.
  • Each link description starts with an uppercase character and ends with a period.
    Example: - [AVA](…) - JavaScript test runner.
  • Drop all the A / An prefixes in the descriptions.
  • Consistent naming. For example, Node.js, not NodeJS or node.js.
• Doesn't include a Travis badge.
  You can still use Travis for list linting, but the badge has no value in the readme.

All of the easy stuff is done; what is left now is to go through each item and conform it to the new template, and make it look beautiful.
