#320 Show and mark differently deleted files in arhive details dialog

[Lafcina]

Hi, adding support for deleted files in arhives is great new feture, thank you.
Also marking changed/unchanged files with different colors (black/grey) in archive details dialog is great old feature.
Next useful future would be to mark deleted files in arhive details dialog. Moste descriptive if they marked in black strikethrough font or, if that's not possible with different color like red.

Thank you !
