Fortune client example - list all IP addresses

Browse Source 
The first IP address on the machine might not be a usable one.
Changed the QLineEdit to a QComboBox, and populated it with
all IP addresses of the machine, along with the machine names
if they are configured.

Task-number: QTBUG-13121
Change-Id: I7c443f5ce6efb0d0b525c5abad1671d3dcbba33c
