OE-6186 - Remove BOTH eyes option
OE-6186 - Remove BOTH eyes option

Remove BOTH eyes option for Cataract Operations, and based on flag.

Added opbooking_disable_both_eyes = true to common.php
Added check in form_Element_OphTrOperationbooking_Operation.php that subspecialty is Cataract and that opbooking_disable_both_eyes is true.

So if a Op Booking is being made with a Cataract Subspecialty then the BOTH will not display.  If any other booking is being made then BOTH will be available.

If common.php is altered to make opbooking_disable_both_eyes set to false then BOTH eyes will be an option for all subspecialties Operation Booking.
