[evolution] String change in mail/importers/ code

[Milan Crha <mcrha redhat com>]

        Hi,
I committed a change [1] for bug #744541 [2] which corrects two 
strings. It makes one ngettext-aware:
   ngettext ("%d Address", "%d Addresses", count)
and another adds plural to a 'contact' word:
   "Import mail and contacts from KMail."
The later string is included in the sources twice.
        Bye,
        Milan.
