Added command line options

I've added two command line options: SEASON and GAME_TYPE (both required) that specifies the, well, season and game type. Additionally I've added a third optional command line option GAME_ID to grab specific reports for one game.

I added the ARIZONA COYOTES to the teams table, though their team_id value is NULL because I don't know it  yet.

Updated the schema to add some foreign key constraints.
