Add natives and stocks to get the ADT array of items that the player has

[IL0co]

/**

 *	@param size				Optional param to store array size
 *	@param category			Optional parameter to indicate the category from which to take

	size = Shop_FillArrayByClientItems(client, _shop_array, category);
	return _shop_array;

*/
native int Shop_FillArrayByClientItems(int client, ArrayList array, char[] category = "");

And also add the "category" parameter to these natives and stocks:

/**
 *	Fills an adt_array by the item ids. Note that array is cleared before being filled
 *	-
 *	@param array			ADT array to use
 *	@param category			Optional parameter to indicate the category from which to take

*/
native int Shop_FillArrayByItems(ArrayList array, char[] category = "");

/**
 *	Creates and ADT array of item ids
 *	-
 *	@param size			Optional param to store array size
 *	@param category			Optional parameter to indicate the category from which to take
 *	-
 *	@return ArrayList
*/
stock ArrayList Shop_CreateArrayOfItems(int &size = 0, char[] category = "")
{
	ArrayList _shop_array = new ArrayList();
	size = Shop_FillArrayByItems(_shop_array);
	return _shop_array;
}
