Nba-scraper

updated headers so they work with the current nba apis

Scraper has been tested for all available NBA games and patched to fix all bugs for individual games that the original scraper did not work on.

* Scraper now scrapes all seasons back to 1999-2000
* Removes x,y locations from events as not available in past seasons. For shots you can still pull them from the nba shot api
* Improved scraping speed cutting scraping times per game in half
* Fixed issue where passing a file name to write to play by play to disk caused an error

Fixed issue where scraper wouldn't run in windows because of lack of Home directory

Fixed an issue with event teams being declared incorrectly and offensive rebounds being calculated incorrectly

* Fixed issue with offensive rebounds not calculating correctly
* Fixed issue with way points are calculated with free throws
* Fixed issues with calculating team lineups for players who don't have any events they did while in the game
