gridsort: re-did the column resizing

- introduced XGridColumn.Flexibility, determining to which degree the column is resized during auto-column-resizing
- removed XGridColumn.PreferredWidth - there really is no need for this anymore now
- documented the relationship between XGridColumn.Flexibility and XGridColumn.Resizeable
- re-implemented TableControl_Impl::impl_ni_updateColumnWidths, with (hopefully) less magic
