fix etlegacy/wolfet, warsow and q3rally server query

[illwieckz]

Hi, three fixes from the XQF project:

• fix warsow qstat.cfg breaking getting servers for any game. The issue is apparently that Q2S doesn't have status2 packet. So use Q3S, which some other id tech 2 games already use (such as Nexuiz). https://github.com/XQF/xqf/commit/ee2a392f150251b33a1ebda5cf2874290feaa181 by @zturtleman
• use dpmaster gamename when requesting servers for q3rally https://github.com/XQF/xqf/commit/ce32b3608a912bb78d1b6faafc62504effdf62e8 by @zturtleman
• allow xqf/qstat to query empties and full wolfet/etlegacy servers https://github.com/XQF/xqf/commit/f63633570f8ca17763ff430e851e592e1794289b by @illwieckz
