Bug 9044: (follow-up) restore the toolbar menu items

This patch adds the following items back to the cataloging
toolbar:

- Edit items in batch
- Delete items in a batch

My rationale: the question of the best UI for selecting items for
batch operations is not yet settled.  Adding the ability to select
items from the bib details page is indeed useful, but as currently
implemented, it can hide the availability of the batch
edit/deletion operations if no item is yet selected.  Although
having both the toolbar items and the links that display when an
item is selected is a bit redundant, for now I think we can live
with that until we get more eyes on the UI.
