#49 Advanced Lan search dialog doesn't remove deselected games

[Terry]

If you go into the advanced Lan search dialog and
deselect a bunch of games, some still continue to be
searched for.

In my case, I have Steam, UT2004, RTCW, CoD and
Doom3. All were selected and I unselected all but
UT2004. Afterwards I saw that quake3 was still being
checked for in the Lan search.
