Add fzf.vim

https://github.com/junegunn/fzf.vim provides commands like Ag to search content in all files, but this project only supports FZF command only.

Thanks for using my configuration. I've removed fzf.vim from my config and replaced it with telescope.nvim. I've been trying out new nvim lua plugins and telescope was definitely one that caught my attention. It's written in pure lua and uses a native c port of fzf as the sorter. Moving forward, I plan to explore more lua plugins and shift towards using pure lua in my configuration 😄
