v6.5.0

Behaviour changes

• admin: Pasting a list replaces its items with the pasted ones instead of appending them, like pasting an item replaces its content. The creatable setting of the list's forms doesn't limit the pasted items anymore, and items of forms that the list lacks are left out as before.

Fixes

• admin: context.getValueAt() finds the parent items of the items that lists load in callbacks that deserializing them calls, e.g. options of selects.
• admin: Fields whose empty value isn't null, e.g. lists, keep null with default: null, instead of replacing it with their empty value.
