Bug 11821: disable catalog edit menu items and provide explanations when actions cannot be done

Biblio edit menu items which are disabled should trigger a tooltip
on hover and an alert on click with explanations. This patch implements
this for the relevent menu items.

To test, apply the patch for Bug 11829 if necessary. Find a record which
has no items attached. Test the following views:

- Normal
- MARC
- Labeled MARC
- ISBD
- Items

Test these Edit menu items:

- Edit items in a batch
- Delete items in a batch
- Delete all items

Hovering over these menu items should trigger an explanatory tooltip.
Clicking the menu items should trigger a similar alert.

Next, locate a title with items attached. On the same pages above, test
the Edit -> Delete record menu item. Hovering should trigger an
explanatory tooltip. Clicking it should trigger a similar alert.
