Packer plugins system enhancement

It'd be helpful with an OpenArchiveEx function that'd return a message along with the error, so that TotalCmd can display this message along with the 'error in archive' thingus

Sometimes it's useful to know why the archive can't be opened, but displaying an additional message seems superflous...

The reason why this isn't done is the translation issue - plugins would have to be translated to various languages.

Hmm.. That's not a major problem... I always get messages like "Do you really want to do this?" with buttons that say "Ja" and "Nej" in swedish, and I think it's the same for every Windows user
