Due to popular demand and support review we have added the possibility to undo the choice of destroying or donating an embryo to research. Previously this action permanently locked the embryo but choosing the code "DestructionRevoke" in the configuration order and choosing a time limit now gives the possibility to revoke the action during the set time period.

The revoke functionality has been implemented for:
- Destruction of fresh oocytes/embryos
- Donation of fresh oocytes/embryos to research
- Destruction of frozen oocytes/embryos
- Donation of frozen oocytes/embryos
- Destruction of thawn embryos
- Thawn embryos marked as "not found" upon thawing

The revoke button will be displayed during the specified time period and makes it possible to unlock the embryo. Once the time limit has been reached the button will dissapear and the normal checkbox will be displayed.
