Ability to add/detach entire groups as key children

[OlayaTapestrySupport]

From now on, you will be able to attach and detach entire groups of children as key children to your staff members from control panel > manage staff > manage key children > edit relationship by the corresponding staff member > groups.

This feature will allow you to use the groups that you created from 'manage groups' to attach the children in that group to one member of staff as key children in a much quicker way, rather than having to do so one child at a time. You will also be able to detach entire groups with just one click.
