Fix issues with 2014 data, add support for Double-A, and add a switch for game type

While running the code on 2014 data, there were a few different errors.  These changes are what I needed to run the code successfully on all games in 2014.  In particular, there was a play or two with four events, there are Unicode strings that causes some of the database queries to error out, and there is a stadium with more than thirty characters.

In addition, I added support for Double-A and added a switch for game type, as I wanted to be able to have a database with just regular season data and another one with just spring training data, etc.
