do not show identical skipped item when 'Show identical items' is unchecked

[Petewg]

when View->Show identical items is unchecked
(actually it means hide identical)
and View->Show skipped items is checked
the identical skipped items get displayed,
something that negates the previous filter
(that is, hide identical ), which filter, in my opinion,
is stronger and hence it should take precedence,
since it's related to the core functionality of Winmerge (comparison) .

Unfortunately, skipped files are not compared, so we cannot determine whether they are identical.
Therefore, the "Show identical items" option cannot apply to skipped files. It only affects items that were actually compared.
