VIM: Reinstall NERDTree

Nerdtree is a rather slow, but extremely useful plugin. So I made the decission to reinstall it, but don't launch it on startup but with a keybinding. Signed-off-by: Tobias Manske <tobias.manske@mailbox.org>

+4.1.0
+    features:
+    - NERDTreeFind to reveal the node for the current buffer in the tree,

+    - fix a bug where the script ignored directories whose name ended in a dot,
+      thanks to Aggelos Orfanakos for the patch.
+    - fix a bug when using the x mapping on the tree root, thanks to Bryan
+      Venteicher for the patch.
+    - fix a bug where the cursor position/window size of the nerd tree buffer
+      wasnt being stored on closing the window, thanks to Richard Hart.
+    - fix a bug where NERDTreeMirror would mirror the wrong tree
+
+3.1.1
+    - fix a bug where a non-listed no-name buffer was getting created every
+      time the tree windows was created, thanks to Derek Wyatt and owen1
+    - make <CR> behave the same as the 'o' mapping
+    - some helptag fixes in the doc, thanks strull

+    - add mappings to open files in a vsplit, see :help NERDTree-s and :help
+      NERDTree-gs
+    - make the statusline for the nerd tree window default to something
+      hopefully more useful. See :help 'NERDTreeStatusline'
+    Bugfixes:
+    - make the hijack netrw functionality work when vim is started with "vim
+      <some dir>" (thanks to Alf Mikula for the patch).
+    - fix a bug where the CWD wasnt being changed for some operations even when
+      NERDTreeChDirMode==2 (thanks to Lucas S. Buchala)
+    - add -bar to all the nerd tree :commands so they can chain with other
+      :commands (thanks to tpope)
+    - fix bugs when ignorecase was set (thanks to nach)
+    - fix a bug with the relative path code (thanks to nach)
+    - fix a bug where doing a :cd would cause :NERDTreeToggle to fail (thanks nach)
+
+
+3.0.1
+    Bugfixes:
+    - fix bugs with :NERDTreeToggle and :NERDTreeMirror when 'hidden
+      was not set
+    - fix a bug where :NERDTree <path> would fail if <path> was relative and
+      didnt start with a ./ or ../  Thanks to James Kanze.
+    - make the q mapping work with secondary (:e <dir>  style) trees,
+      thanks to jamessan
+    - fix a bunch of small bugs with secondary trees
+
+    More insane refactoring.
+
+3.0.0
+    - hijack netrw so that doing an :edit <directory>  will put a NERD tree in
+      the window rather than a netrw browser. See :help 'NERDTreeHijackNetrw'
+    - allow sharing of trees across tabs, see :help :NERDTreeMirror
+    - remove "top" and "bottom" as valid settings for NERDTreeWinPos
+    - change the '<tab>' mapping to 'i'

+The NERDTree
+=============
+
+Introduction
+------------
+
+The NERDTree is a file system explorer for the Vim editor. Using this plugin,
+users can visually browse complex directory hierarchies, quickly open files for
+reading or editing, and perform basic file system operations.
+
+This plugin can also be extended with custom mappings using a special API. The
+details of this API and of other NERDTree features are described in the
+included documentation.
+
+![NERDTree Screenshot](https://github.com/scrooloose/nerdtree/raw/master/screenshot.png)
+
+Installation
+------------
+
+#### [pathogen.vim](https://github.com/tpope/vim-pathogen)
+
+    git clone https://github.com/scrooloose/nerdtree.git ~/.vim/bundle/nerdtree
+
+Then reload Vim, run `:helptags ~/.vim/bundle/nerdtree/doc/` or `:Helptags`, and check out `:help NERDTree.txt`.
+
+
+#### [apt-vim](https://github.com/egalpin/apt-vim)
+
+    apt-vim install -y https://github.com/scrooloose/nerdtree.git
+
+F.A.Q.
+------
+
+> Is there any support for `git` flags?
+
+Yes, install [nerdtree-git-plugin](https://github.com/Xuyuanp/nerdtree-git-plugin).
+
+---
+
+> Can I have the nerdtree on every tab automatically?
+
+Nope. If this is something you want then chances are you aren't using tabs and
+buffers as they were intended to be used. Read this
+http://stackoverflow.com/questions/102384/using-vims-tabs-like-buffers
+
+If you are interested in this behaviour then consider [vim-nerdtree-tabs](https://github.com/jistr/vim-nerdtree-tabs)
+
+---
+> How can I open a NERDTree automatically when vim starts up?
+
+Stick this in your vimrc: `autocmd vimenter * NERDTree`
+
+---
+> How can I open a NERDTree automatically when vim starts up if no files were specified?
+
+Stick this in your vimrc:
+
+    autocmd StdinReadPre * let s:std_in=1
+    autocmd VimEnter * if argc() == 0 && !exists("s:std_in") | NERDTree | endif
+
+Note: Now start vim with plain `vim`, not `vim .`
+
+---
+> How can I open NERDTree automatically when vim starts up on opening a directory?
+
+    autocmd StdinReadPre * let s:std_in=1
+    autocmd VimEnter * if argc() == 1 && isdirectory(argv()[0]) && !exists("s:std_in") | exe 'NERDTree' argv()[0] | wincmd p | ene | endif
+
+This window is tab-specific, meaning it's used by all windows in the tab. This trick also prevents NERDTree from hiding when first selecting a file.
+
+---
+> How can I map a specific key or shortcut to open NERDTree?
+
+Stick this in your vimrc to open NERDTree with `Ctrl+n` (you can set whatever key you want):
+
+    map <C-n> :NERDTreeToggle<CR>
+
+---
+> How can I close vim if the only window left open is a NERDTree?
+
+Stick this in your vimrc:
+
+    autocmd bufenter * if (winnr("$") == 1 && exists("b:NERDTree") && b:NERDTree.isTabTree()) | q | endif
+
+---
+> Can I have different highlighting for different file extensions?
+
+See here: https://github.com/scrooloose/nerdtree/issues/433#issuecomment-92590696
+
+---
+> How can I change default arrows?
+
+Use these variables in your vimrc. Note that below are default arrow symbols
+
+    let g:NERDTreeDirArrowExpandable = '▸'
+    let g:NERDTreeDirArrowCollapsible = '▾'
