* This is an attempt to resolve mantis 4437 by using SqliteAdapter type statements instead of blanket SQL statements. The hope is that this makes SQLite work on Linux/Mono again. Re: http://opensimulator.org/mantis/view.php?id=4437
* Added a 'Create Update Statement' method that takes two fields for a primary key * Added an Update and Delete command for parcels and land access list table rows.
