Edit the README file

Two key changes were made:

 1. A screenshot was added for visual appeal.
 2. The massive (and noisy) feature list was removed. This
    information is adequately covered in the docs.

Fixes #573.

The NERDTree The NERDTree
============= =============
Intro Introduction
----- ------------
The NERD tree allows you to explore your filesystem and to open files and The NERDTree is a file system explorer for the Vim editor. Using this plugin,
directories. It presents the filesystem to you in the form of a tree which you you can visually browse complex directory hierarchies, quickly open files for
manipulate with the keyboard and/or mouse. It also allows you to perform reading or editing, and perform basic file system operations. This plugin can
simple filesystem operations. also be extended with custom mappings using a special API. The details of this
API and other NERDTree features is described in the included documentation.
The following features and functionality are provided by the NERD tree: ![NERDTree Screenshot](https://github.com/scrooloose/nerdtree/raw/master/screenshot.png)
* Files and directories are displayed in a hierarchical tree structure
* Different highlighting is provided for the following types of nodes:
* files
* directories
* sym-links
* windows .lnk files
* read-only files
* executable files
* Many (customisable) mappings are provided to manipulate the tree:
* Mappings to open/close/explore directory nodes
* Mappings to open files in new/existing windows/tabs
* Mappings to change the current root of the tree
* Mappings to navigate around the tree
* ...
* Directories and files can be bookmarked.
* Most NERD tree navigation can also be done with the mouse
* Filtering of tree content (can be toggled at runtime)
* custom file filters to prevent e.g. vim backup files being displayed
* optional displaying of hidden files (. files)
* files can be "turned off" so that only directories are displayed
* The position and size of the NERD tree window can be customised
* The order in which the nodes in the tree are listed can be customised.
* A model of your filesystem is created/maintained as you explore it. This
has several advantages:
* All filesystem information is cached and is only re-read on demand
* If you revisit a part of the tree that you left earlier in your
session, the directory nodes will be opened/closed as you left them
* The script remembers the cursor position and window position in the NERD
tree so you can toggle it off (or just close the tree window) and then
reopen it (with NERDTreeToggle) the NERD tree window will appear exactly
as you left it
* You can have a separate NERD tree for each tab, share trees across tabs,
or a mix of both.
* By default the script overrides the default file browser (netrw), so if
you :edit a directory a (slightly modified) NERD tree will appear in the
current window
* A programmable menu system is provided (simulates right clicking on a node)
* one default menu plugin is provided to perform basic filesystem
operations (create/delete/move/copy files/directories)
* There's an API for adding your own keymappings
