unexpected gnacs hacking session

-for some reason, venue name wasn't coming through fsq output anymore. fixed.

-added tests to twacscsv.py so a bare gnacs.py call will output useful fields from all publishers (no more GNIPERROR)

-test script now looks at the data in the data/ dir and calculates how much stuff is there. the user now only has to add up the number of expected lines and drop it in at the bottom. still a hack, but it's at least correct now!
