Apache2 service was not restarting properly since Ubuntu14.04 which resulted in race conditions. This is explained in detail in the script. Adds a work around to fix apache2 race invoked by lack of www-browser virtual package linking to a basic text browser. Adding w3m before hand to avoid any future issues. Ofcourse lynx or links works here too. Also provides more systematic stopping and starting of apache service for eliminating restart/start-stop race issues.
