OVERVIEW: Can now retrieve trips in JSON

app.js - removed line that was causing errors (reason unknown, sorry)
secret.js - using a different DB now (named "barbosa") to make it clear what DB we're using.
styles.css - SHA hash and file length changed automagically, committing to be safe.
Trip.js - removed extra whitespace.
trip.js - Removed plurarlization so the comments were actually correct.
        - showTrip function now returns a JSON string with the trip info when we go to /trip/:id
        - trip actually saves to the mongodb collection and returns with a JSON string that includes the tripID
