fix warsow qstat.cfg breaking getting servers for any game

Warsow qstat cfg caused an error and prevented getting servers for any game
(using qstat 2.11 at least).

    qstat.cfg line 254: Cannot set status2 packet; extend game type does not define a status2 packet

The issue is appearently that Q2S doesn't have status2 packet. So use Q3S,
which some other id tech 2 games already use (such as Nexuiz).
use dpmaster gamename when requesting servers for q3rally, fix #104
