Bug 8161 - Cataloging home page should be accessible to users with permission to edit catalog or edit items

This patch modifies the permissions required to access the cataloging
home page (addbooks.pl) so that the user requires edit_catalogue,
edit_items, or fast_cataloging permission.

Users with only edit_catalogue permission will only see biblio edit
links. Users with edit_items permission will only see item edit
links. Users with fast_cataloging permission will only be able to
view information about contents of the catalog--useless for them
but I'm not sure how better to handle it.

To test, log in as a user with each of the above permissions
enabled separately and in combination and test access.
