Subject: LibOverride: Add option to Hierarchy Creation to get all data
 user-editable by default.

Avoids having to manually enable data-blocks for user-edition when you
do not care about what should be edited by whom. Similar to default
behavior before introduction of system overrides (aka non-user-editable
overrides).
