#82 Threading and resorting of columns

[Axel Katerbau]

When changing the sorting to "flags", "author", "subject", "date" and then toggling to threading then bad things happen (two author cols) and the log says:

2002-02-08 10:11:52.737 Ginko[294] *** NSOutlineView cannot remove outlineTableColumn with removeTableColumn:. Use setOutlineTableColumn: instead.
