Check for existing contact when adding a new contact

eM Client should check if a contact is already existing when adding a new contact.

eM Client could for example check the following fields:

* first name + last name

* e-mail address

* phone number.

If a contact is already existing with the same values for at least 1 of these fields, eM Client could give a warning.

Hi, this idea sounds interesting and useful. After discussion I will keep it open for other users to up vote this idea.
I will also mark it under consideration.
