Addition of pitch_type code

It's not pretty, but I added in the code necessary to pull down the pitch_type data. It now access the pitch count webpage first, pulls the data, then accesses the second page and pulls the pitch_type data. It's not perfect as it actually has cut out some of the pitch count data for some reason. Perhaps a problem with having 2 items named 'url' even though they are accessed in order? Or a problem with the updated row command?

I also added a start date function that lists it as 1900-01-01. None of the players played at this time, but I believe the website just reads that date as the first possible date. I'm going to test it here shortly.
