Fixed file name for launcher.py in the fix_injuries call.
Added indexes on fantasy_points and defense_vs_position

Added index on game_totals_basic_id for fantasy_points.  This was
absolutely necessary because this table is usually joined with
game_totals_basic on the game_totals_basic_id column, so making sure a
table scan didn’t occur is big.

Also added index on stat for defense_vs_position.
