Title: Filter Out Contacts Without Phone Numbers

Because Facebook can now add contacts directly to your phone's contact list (which may or may not contain telephone numbers depending on whether or not a Facebook user has chosen to list his/her phone number in the Facebook account), I found a great deal of duplicate contacts appearing when I ran this code on my device. Thus I added a simple filter (when using the telephone lookup option) to remove all contacts that do not have a phone number listed.
