[imp] Trash Drafts and Sent folder

[Dominique LALOT]

Hello,

I would like to get these folders working like Thunderbird:

The true folders are Sent,Drafts,Trash and they are only translated in 
non-english language.
In prefs.php, you have _("Drafts") which will be replaced by Brouillons 
in french

How can I do that?

Thanks

Dom
