 - refactor all `system` call to `libuv` functions, with better error management

+Dictionnary, if your terminal or font doesn't support certain unicode
+character, the tree UI might be messed up. The following configuration
+can disable icons per type:
+>
+    let g:lua_tree_show_icons = {
+	\ 'git': 1,
+	\ 'folders': 1,
+	\ 'icons': 1
+	\}
+
+Can be one of `1` and `0` for each key. By default the tree will try
+to render the icons. The `icons` key can only work if `vim-devicons`
+is installed and in your |runtimepath|
