API updates

A number of changes to the API schema were recently introduced with the last release.
These changes are only additions to the existing schema, and do no affect existing apps. In other words, they're fully backwards-compatible.

Here is a complete list.

• new "gender" field in the Customer object
• new "privateEvent" field in the Booking object
• new query parameter "mode" to relax some checks, in POST /bookings and PUT /bookings
• new way to specify BookingOption via id instead of name
• product options are now included in the product description , in /settings/products
• new fields totalPayable, applicableMoneyCredit, applicableGiftVoucherCredit, applicablePrepaidCredits in the Hold object
