Further sanitized the app

Removed more functions, etc. that won't be used in the future from
script.js. Also added comments. Deleted 3 files that were left over
from CMU Carnival. Updated README because I forgot to add the 'id' and
'important' fields for events.
Cleaned up HTML pages

Cleaned up the <head> section of the html files. Stopped loading files
from alexstern.com. Removed some dorm related code.
