We should improve the wording on the alert boxes shown when a node is marked for deletion. The current message is somewhat technical.

I've suggested to unify both boxes (for a node, which will be deactivated and marked for deletion as well as for one, which will only be marked for deletion), but show them in both cases and to show the wording to this:

"The page and its sub pages will be marked for deletion. They will
be deleted from all instances, once you activate this change."
OK, Cancel
