Corrections and additions

Added config files: php.ini, www.conf, php-fpm.conf, and sysctl.conf.

Added nginx user and added cd statement for nginx install.

Corrected find and replace statement within Fail2Ban install.

Added memcached install within memcache section (it was only installing the PHP->memcache module, not memcache itself).

Corrected paths in the Config and Harden server section. Also changed all file changes to move included files instead of trying to find and replace and/or append existing files on the server.
