Ranger integration in vim and neovim

Install it with your favorite plugin manager. Example with vim-plug:

    Plug 'francoiscabrol/ranger.vim'

If you use neovim, you have to add the dependency to the plugin bclose.vim:

    Plug 'rbgrouleff/bclose.vim'

The default shortcut is f (\f by default) but you add a new mapping with this line:

    map <leader>f :call OpenRanger()<CR>
