Settings Changes:

- Added important info in settings for users regarding access to their Facebook accounts and using public events

Server Changes:
- Getting basic event data, cover photo, guest stats, and event feed through 4 different calls to the server (which calls Facebook) is working. 4 seperate asynchronous calls allows for processing of data on client side while waiting for server to return requests

- Added security to prevent outsiders from accessing random Facebook events by changing the url. Only events with IDs saved in the database for the user can be accessed with the modal link.
