Initial commit

- server not getting message
Finished emergency feature in the server.js file
To-do show emergency dialog
Worked on getting the emergency page to show up over the original page. Work still in progress
Finished the Zombie Apocalypse App. Added in the Emergency feature and added in a button, only available from the admin page, to dismiss the Emergency message.
Refactored code to remove comments and unused variables. Also had to duplicate the emergencyResolved socket event to ensure that the client was also removing the overlay when an emergency has been resolved.
