Base16 themes now available

[niklaas]

I created a base16 template and the corresponding colours for blink. You can read more about base16 and its build mechanism.

Feel free to add the themes to this repository/the gallery. I would love to provide screenshots but it's a lot of them. Maybe you can create the screenshots with a script? That said, previewing the themes is possible over here: https://chriskempson.github.io/base16 .
