[dev] [imp-patch] prevent duplicate contacts from addressbook

[Chuck Hagenbuch]

Quoting Francois Marier <francois at nit.ca>:

> Here's a small Javascript patch for IMP.  The annoyance it fixes is
> the following:
>
> After having clicked on the "Addressbook" button in the Compose
> window, it is possible to add several times the same contact to the
> listbox on the right.
>
> This patches only allows a contact to move to the right listbox if it
> is not already in there.  Thus clicking repeatedly on the "To >>"
> button will not fill the right listbox with useless entries.

Committed, thanks!
