Christoph Oelckers cf74118d53 - fixed the extremely long standing bug that Lost Souls didn't reacquire their target when slamming into something. 
This was one of that annoying old design mistakes where Doom and Heretic features were poorly merged together. The Heretic Gargoyle uses very similar coding but performs a subtly different action when actually hitting another actor. This different action was made the default, even for the Lost Soul.
It has now been changed that both monsters use their original action, being distinguished by an actor flag. For compatibility with custom definitions Heretic's behavior, which has been the default in ZDoom will be the preferred one. The one of the Lost Soul can be reactivated by a flag.

// NOTES: AActor
//
// Actors are used to tell the refresh where to draw an image,
// tell the world simulation when objects are contacted,
// and tell the sound driver how to position a sound.
//
// The refresh uses the next and prev links to follow
// lists of things in sectors as they are being drawn.
// The sprite, frame, and angle elements determine which patch_t
// is used to draw the sprite if it is visible.
// The sprite and frame values are almost always set
// from state_t structures.
// The statescr.exe utility generates the states.h and states.c
// files that contain the sprite/frame numbers from the
// statescr.txt source file.
// The xyz origin point represents a point at the bottom middle
// of the sprite (between the feet of a biped).
// This is the default origin position for patch_ts grabbed
// with lumpy.exe.
// A walking creature will have its z equal to the floor
// it is standing on.
//
// The sound code uses the x,y, and sometimes z fields
// to do stereo positioning of any sound emitted by the actor.
//
// The play simulation uses the blocklinks, x,y,z, radius, height
// to determine when AActors are touching each other,
// touching lines in the map, or hit by trace lines (gunshots,
// lines of sight, etc).
// The AActor->flags element has various bit flags
// used by the simulation.
//
// Every actor is linked into a single sector
// based on its origin coordinates.
// The subsector_t is found with PointInSector(x,y).
// The sector links are only used by the rendering code,
// the play simulation does not care about them at all.
//
// Any actor that needs to be acted upon by something else
// in the play world (block movement, be shot, etc) will also
// need to be linked into the blockmap.
// If the thing has the MF_NOBLOCK flag set, it will not use
// the block links. It can still interact with other things,
// but only as the instigator (missiles will run into other
// things, but nothing can run into a missile).
// Each block in the grid is 128*128 units, and knows about
// every line_t that it contains a piece of, and every
// interactable actor that has its origin contained.
//
// A valid actor is an actor that has the proper subsector_t
// filled in for its xy coordinates and is linked into the
// sector from which the subsector was made, or has the
// MF_NOSECTOR flag set (the subsector_t needs to be valid
// even if MF_NOSECTOR is set), and is linked into a blockmap
// block or has the MF_NOBLOCKMAP flag set.
// Links should only be modified by the P_[Un]SetThingPosition()
// functions.
// Do not change the MF_NO* flags while a thing is valid.
//
// Any questions?
