Trailing white space causing syntax errors

[jcwong86]

Using the current BART gtfs (http://bart.gov/dev/schedules/google_transit.zip), it happens to have two trailing white space lines in the stops table and the transfers table which causes script to stop uploading tables beyond there. When I deleted the white space it fixed the problem. I don't think most feeds have these trailing spaces, but maybe the program should end at the last full line.

These errors go away when the whitespace is deleted and the program is re-run...
