Passes all tests and QA script.
This feature is a little controversial as it removes
the batch edit/delete options from the menu and moves them
to the item table, additionally controlled by a system
preference. Maybe later on, we can think about the UI a bit
more, but it works nicely.

Tested with.
- SeparateHoldings and SeparateHoldingsBranch activated/deactivated.
- Search filters.
- None, both, or one of the permissions.
