Add eyebrowse recipe

This is the recipe of [eyebrowse](https://github.com/wasamasa/eyebrowse), a global minor mode I wrote and maintain. It manages window configurations in a simpler manner than using `C-x r w` and `C-x r j` directly and displays their state in the modeline. The behaviour is modeled after [ranger](http://ranger.nongnu.org/) and can be optionally enabled.

I've already done tests with [quelpa](https://github.com/quelpa/quelpa) which means merging should go without a hitch.
