Setting season and league for widget
Most of the widgets require to have league or season to be set. It is done by passing season_id or league_id paramaters to widgets. If only league_id parameter is passed, default season is taken. If only season_id is passed, league_id is calculated automaticaly, this is possible because in BasketHotel all seasons are children of leagues, meaning "season 2010-2011" in "Mens league" and "season 2010-2011" in "Womens league" will completely differend season and will have differend ids. If both "season_id" and "league_id" will be passed to widget, one has to make sure, that season is a child for league set, otherwhise widget will throw an error.
