Feb 28, 2012: Added three FK constraints for QA (for owner/borrowernumber in virtualshelves, shelfcontents and shelfshares). Tested update again.
Also removed the note about public lists, made obsolete by earlier adjustments for comments from Owen.
Feb 29, 2012: Rebased. Added an update statement to replace invalid borrowernumbers with null in virtualshelves before adding constraint and added a delete statement for private lists without owner now (as a result of the first step). Tested it again.

Bug 7310: Code changes for Improving list permissions

This lays the foundation for further changes for report 7310.
Implements following points from the wiki page List permissions:
1) Preference that controls if users may create public lists in opac.
2) New add/delete own/delete other permissions per list.

Code has been changed (in some cases refactored). New permissions are not yet visible; with this patch current functionality is kept as much as possible while resolving several issues, improving permissions and extending the code for further developments (using the new permissions and sharing lists).

Feb 23, 2012 (revision): Changed defaults for new lists. Could also remove routine GetRecentShelves by using GetSomeShelfNames in catalogue/search.pl just as opac-search.pl already did. (More consistent.)

Test this patch by trying to delete items from a public list that someone else created (so you do not have sufficient permissions). Check the warning.
