Editing FindTracer

{{codepointer|description=Search for a valid seek target, if the calling actor doesn't already have one. Particularly useful for player projectiles.
|usage='''A_FindTracer'''(''field_of_view'', ''search_distance'')
|parameters=
*''field_of_view'': the field of view relative to calling actor's angle to search for targets in. Default: 360 degrees (all around)
*''search_distance'': distance to search in map blocks (of 128 units each). Default: 10
|notes=This will prefer aiming for targets closer to its current angle, then fan out as necessary until ''field_of_view'' is reached. It will avoid locking on the shooter or allied actors.}}
