Tweaks to PyPI packaging and GitHub front-page

PyPI changes:
- Changed overall cmd2 description
- Fixed pip install warning due to unknown "docs_require" distribution option
- No longer include examples and tests in PyPI *.tar.gz package

GitHub README.md changes:
- Changed top-level cmd2 description
- Improved labels on build badges so it says "unix build: passing" and "windows build: passing" instead of two "build passing" badges right next to each other
- Reorganized layout a little to hopefully do a better job explaining what cmd2 is earlier

-cmd2 is a tool for writing interactive command-line applications for Python 2.7 and Python 3.3+.  It is based on the
-Python Standard Library's [cmd](https://docs.python.org/3/library/cmd.html) module, and can be used any place cmd is used simply by importing cmd2 instead.  It is
-pure Python code with the only 3rd-party dependencies being on [six](https://pypi.python.org/pypi/six), [pyparsing](http://pyparsing.wikispaces.com),
-and [pyperclip](https://github.com/asweigart/pyperclip).
+cmd2 is a tool for building interactive command line applications in Python. Its goal is to make it quick and easy for developers to build feature-rich and user-friendly interactive command line applications.  It provides a simple API which is an extension of Python's built-in [cmd](https://docs.python.org/3/library/cmd.html) module.  cmd2 provides a wealth of features on top of cmd to make your life easier.
+
+Main Features
+-------------
+- Searchable command history (`history` command and `<Ctrl>+r`)
+- Text file scripting of your application with `load` (`@`) and `_relative_load` (`@@`)
+- Python scripting of your application with ``pyscript``
+- Run shell commands with ``!``
+- Pipe command output to shell commands with `|`
+- Redirect command output to file with `>`, `>>`; input from file with `<`
+- Bare `>`, `>>` with no filename send output to paste buffer (clipboard)
+- `py` enters interactive Python console (opt-in `ipy` for IPython console)
+- Multi-line, case-insensitive, and abbreviated commands
+- Special-character command shortcuts (beyond cmd's `@` and `!`)
+- Settable environment parameters
+- Parsing commands with flags
+- Unicode character support (*Python 3 only*)
+- Good tab-completion of commands, file system paths, and shell commands`
+- Python 2.7 and 3.3+ support
+- Linux, macOS and Windows support
+- Trivial to provide built-in help for all commands
+- Built-in regression testing framework for your applications (transcript-based testing)

-cmd2 provides the following features, in addition to those already existing in cmd:
 
-- Searchable command history
-- Load commands from file, save to file, edit commands in file
-- Multi-line commands
-- Case-insensitive commands
-- Special-character shortcut commands (beyond cmd's `@` and `!`)
-- Settable environment parameters
-- Parsing commands with flags
-- Redirection to file with `>`, `>>`; input from file with `<`
-- Bare `>`, `>>` with no filename send output to paste buffer
-- Pipe output to shell commands with `|`
-- Simple transcript-based application testing
-- Unicode character support (*Python 3 only*)
-- Tab completion of file system paths for ``edit``, ``load``, ``pyscript``, ``save``, and ``shell`` commands
-- Integrated Python scripting capability via ``pyscript`` and ``py`` commands
-- (Optional) Embedded IPython shell integration via optional opt-in ``ipy`` command
