Qt: Add option to back white line separator for packet list items

This uses one line (on bottom) of items and makes it white.
Seen in Wireshark on some configurations of GTK 2 on Linux,
so backports it to Qt for people who like it.

In my opinion it helps if you use packet list background colors
for frames and you have a lot of following frames with
the same background color.
