 * Revision 1.2  2003/09/29 07:44:26  eilers
 * Improvement of PIM-SQL Databases, but search queries are still limited.
 * Addressbook: Changed table layout. Now, we just need 1/3 of disk-space.
 * Todo: Started to add new attributes. Some type conversions missing.
 *
 * Revision 1.1  2003/09/22 14:31:16  eilers
 * Added first experimental incarnation of sql-backend for addressbook.
 * Some modifications to be able to compile the todo sql-backend.
 * A lot of changes fill follow...
