Refacto: rewrite everything

- The tree is created with libuv functions, which makes it blazingly fast.
- The tree may now be faster than any other vim trees, it can handle directories with thousands of files without any latency at all (tested on 40K files, works flawlessly).
- More solid logic for opening and closing the tree.
- tree state is remembered (closing / opening a folder keeps opened subdirectories open)
- detection of multiple git projects in the tree
- more icon support
- smart rendering
- smart updates
- ms windows support
- gx replacement function running xdg-open on linux, open on macos

 ## Notice
 
-- This plugin does not work on windows.
+This plugin doesn't support windows. \
+This plugin requires [neovim nightly](https://github.com/neovim/neovim/wiki/Installing-Neovim). \
+You can switch to commit `afc86a9` if you use neovim 0.4.x. \
+Note that the old version has less features and is much slower than the new one.
 
 ## Install
 
 Install with [vim-plug](https://github.com/junegunn/vim-plug):
 ```vim
+" master (neovim git)
+Plug 'kyazdani42/nvim-web-devicons' " for file icons
 Plug 'kyazdani42/nvim-tree.lua'
+
+" old version that runs on neovim 0.4.x
+Plug 'kyazdani42/nvim-tree.lua' { 'commit': 'afc86a9' }

+
+This plugin is very fast because it uses the `libuv` `scandir` and `scandir_next` functions instead of spawning an `ls` process which can get slow on large files when combining with `stat` to get file informations.

 ## Features
-- [x] Open file in current buffer or in split with FzF like bindings (`<CR>`, `<C-v>`, `<C-x>`, `<C-t>`)
-- [x] File icons with vim-devicons
-- [x] Syntax highlighting ([exa](https://github.com/ogham/exa) like)
-- [x] Change directory with `.`
-- [x] Add / Rename / delete files
-- [x] Git integration
-- [x] Mouse support
