Fix Github UI/UX yourself, since they are not interested : (
- Adds Link button to Readme editor (select text, press link, paste URL)
- NOTE: If link button doesnt appear on first visit, press F5 when you enter editing readme
- Add checkerboard background for github image viewer (so that you can finally see white+transparent images!) https://gist.github.com/unitycoder/e60f703be8411a5871fc10a8d56aa1d8
