Added new string into Evolution

[Milan Crha <mcrha redhat com>]

	Hello,
I just committed patch for bug #350539 [1] into Evolution, which
contains new string.

In Evolution-data-server part I reused already known strings, from same
source file, but other line number, so I suppose it's not a problem.

	Bye,
	Milan Crha
