User added to license count twice

Prior to this fix, under certain condition, a user may be added to the license count twice.

If Directory Assistance is configured to use a condensed directory catalogue, the user may appear in the main address book and in the directory catalogue.

Under these conditions, Crossware Mail Signature will process each person document individually and will count the user twice to the license count.

With this fix, Crossware Mail Signature is able to check if a user has been previously counted.

This fix was implemented in V4.02.
