Increase kMaxSuperXSprites from 128 to 512. Fix mirror (ROR) intialization so it won't crash if more than 1024 sectors used. Fix random item generator so items that inherits TX ID won't send command at respawn. Fix for things (400 - 433) that affected by modern physics so it won't return to vanilla physics after getting damage. Fix kTeleportTarget so teleported sprites won't stuck in floors or ceilings. Corpses won't gib as gargoyles anymore (gModernMap). kModernCondition: - remove bool comparison (condCmpb). - remove no extra comparison (condCmpne). - remove "else if" search at level start. - add global (game) conditions type. - add more conditions. - make error report a bit more informative. Add more options and damage effects for kModernSpriteDamager. Add more options for kModernMissileGen and allow to spawn projectile on TX ID sprites location. Add more options and vertical wind processing for kModernWindGen. Add more options and effects for kModernEffectGen. Allow kMarkerDudeSpawn to spawn enemies on TX ID sprites location (gModernMap). Allow kModernCustomDudeSpawn to spawn dude on TX ID sprites location. Add Screen and Aim trigger flags for sprites that can be triggered with Sight (gModernMap). Patrolling enemies: - add turn AI state. - add "return back" option for path markers. - add "turning while waiting" option for markers. - make enemies to hear some sounds assuming that player generates and hears it too. - add kModernStealthRegion type to affect current spot progress velocity. - replace AI's CanMove and aiChooseDirection to a better versions. - make flying enemies to not spin around the marker. - treat Phantasm as flying enemy! - allow to continue patrol when falling in water. Fix compile warnings Various minor fixes / cleanup.
