New Shortcode:
Added shortcode [i4w_product] (short form: [i4w_prod])
Added shortcode [i4w_subscription] (short form: [i4w_subs])
Usage: These shortcodes are designed to replace the [i4w_db_prod_nn_FieldName] short codes, which will eventually be deprecated.
BUGFIX:
Several new PHP warnings were displayed on sites whose themes do not suppress them. Fixed.
