Fixed and tested callbacks on functions required to determine most recent raceID
Working to get parallel http requests for headers
Added agent: false to the http request options to speed up the requests (eliminates pooling and keep-alive I believe. Then removed the debug messages.
Used correct constant notation to define the first RaceID of the season in the getCurrentRaceID function
Updated with progress: Fix random successful raceID issue, polish up styling, and test in Litmus.
