Update WordPress to 3.6.1

* Removed htdocs and replaced with latest version of wordpress (3.6.1)
* Moved sample wp-config file to wp-config.php
* Edited wp-config.php to include the services changes (basically to
  match the previous wp-config.php)
  * I left the 'unique phrases' alone and just left the default
    'put your unique phrase here' as text or config values
* Updated README.md to 3.6.1
