The isClass and config checks are done in player_spawnCheck. There is no reason to do that here. Those variables are being passed in an array during the function call. Global variables dayz_spawnZombies and dayz_maxControlledZombies used in spawn checks are adjusted in player_spawnCheck and zombie_generate. There is no reason to save to local variables.
Zeds and loot should not spawn in trader cities by default, regardless
of whether the server uses safe zones.
For servers that do not use safezones, the only other things affected
are salvage and instant kill for vehicle explosions in trader cities.
Neither is a significant issue. Most servers use safezones anyway.
Following d750f57, changed to exitWith so the check is only called once
instead of multiple times. Also no need to call again in
zombie_generate, since that function is only called by
building_spawnZombies which already checks it.
AFAIK there is no performance difference between configFile and
missionConfigFile.
Using missionConfigFile by default simplifies loot scripts and makes the
extra config variable unnecessary. It's one less step for admins to
customize their tables.
