[jet booking] add a filter to is_sold_individually() in WC_Product_Jet_Booking

[breakerh]

I think it would be awesome to add a filter in the is_sold_individually() in WC_Product_Jet_Booking.
This allows people to enable quantity along with the text fields which already have this.

Extending the WC_Product_Jet_Booking brings some unwanted/unexpected behaviour.

Example:

	 /**
	 * Get type.
	 *
	 * Get internal type.
	 *
	 * @access public
	 *
	 * @return string
	 */
	public function get_type() {
		return 'jet_booking';
	}

	/**
	 * Is sold individually.
	 *
	 * Check if a product is sold individually (no quantities).
	 *
	 * @access public
	 *
	 * @return boolean
	 */
	public function is_sold_individually() {
		return apply_filters( 'jet_booking_sold_individually', false, $this ); // <-- Added this filter for is_sold_individually
	}

	/**
	 * Ger virtual.
	 *
	 * Set product as virtual.
	 *
	 * @access public
	 *
	 * @param string $context What the value is for. Valid values are `view` and `edit`.
	 *
	 * @return bool
	 */
	public function get_virtual( $context = 'view' ) {
		return apply_filters( 'jet_booking_get_virtual', true, $this ); // <-- Added this filter for get_virtual
	}

	/**
	 * Is purchasable.
	 *
	 * Returns false if the product cannot be bought.
	 *
	 * @access public
	 *
	 * @return bool
	 */
	public function is_purchasable() {
		return apply_filters( 'woocommerce_is_purchasable', true, $this );
	}

Would really love if this is added, and I think I can make a few people happy after that since we've made a extension which allows customers to use qty together with jet booking..

Thanks for the feedback.

Next 3.3.1 release version of the plugin will have such hooks. For is_sold_individually() will be added WC based woocommerce_is_sold_individually hook that used for such purpose. As for get_virtual() there is no default WC hook so in this case will be added jet-booking/wc-integration/booking-product/get-virtual the naming of the hook stands on our naming standards.

But for the time being plugin will only handle default values from this methods.

Thank you for your understanding.
