linking facebook event to website

[raymondnumbergenerator]

create a model for the facebook event page, so we can change it on the admin panel
it should then fetch date/time/location from the event page and update the necessary information on the website accordingly

also, have eau.berkeley.edu/nightmarket redirect to the current semester's facebook page
(right now eau.berkeley.edu/nightmarket is a page on the current website so feel free to change that to something else)
