Added Check Scripts

Added Supporting Health Check Scripts Accessible via:
http://check.localdomain/check-apache.php
http://check.localdomain/check-mysql.php
http://check.localdomain/check-websites.php

check-mysql relies on credentials to be in .my.cnf within apache's home
dir
check-websites depends on either a hosts file hack or dns to function
properly
check-apache - well if apache is down we can't check it can we? :-)
