Add recipe for evil-snipe

Evil-snipe brings the functionality of vim-sneak and vim-seek to evil-mode. It is a more streamlined alternative to ace-jump or isearch. Put simply, it's vim's f/F/t/T on steroids, and with N character search, but by default is set for 2-character searching. E.g. `shi` will jump to the next occurrence of 'hi'.

This is my first emacs plugin, so any advice would be appreciated!
