Replace objectOutputTableRow() with objectGetTableRow(). Redesign the table output mechanism so

that we fetch a table row from a class instead of letting the class display it. Move adding of
edit/delete links from the classes to the objectManager. Fix a hole in the distribution class
where an uninitialized variable could have been used in the constructor.
