Arca Noae Package Manager: language packs refreshed

All language packs for Arca Noae Package Manager have been refreshed, and a complete French help file has been added (thanks to Guillaume Gay for the translation). The other help files saw minor updates, mainly to correct compilation errors.

The package is available in English with French, German, Italian, and Swedish language packs (more languages to be added). Dutch is coming soon.

This open source utility is available to everyone, free of charge, regardless whether you have an Arca Noae software subscription.

Please review the wiki for important first-time installation notes and other tips.
