Possibility to overwrite the OTA email address in the guest data with the actual email address of the guest provided in the WCI.
For this, we use the email of the first WCI participant and overwrite the email of guest_g of the respective reservation - only if it ends with 'guest.booking.com' or 'm.expediapartnercentral.com'.
This feature can be enabled through the existence of 'webmailwci' in ComboboxList/c_code.
Additionally, a field to save the OTA email can be declared in the control field, eg USER11.
If control is empty, the OTA email is not saved.
