usetrail=<1 or 0>;       
    used to define the units that will have a trail.
trailr=<number>;trailg=<number>; trailb=<number>;
    the trail RGBA color, defaults to white(1,1,1,1).         
traila=<number>;     
    the trail alpha.         
trailwidth=<number>;   
    the width of the trail, required.  
trailframes=<number>;   
    the life time of the trail, defaults to 1.00.
trailblendmode=<0,1,2>;       
    overlay,additive, or subtractive, defaults to 0. 
trailfadealpha=<0 or 1>;        
    used to determine if its alpha will fade over distance, required.  
traildrawinminimap=<0 or 1>;  
    used to determine if it will be drawn on the minimap too.
traildrawshadow=<0 or 1>; 
    used to determine if its shadow will be drawn.
traildrawwater=<1 or 0>;
    used to determine if it will be drawn on the water reflection and refraction too.
trailrendermode=<0,1,2>;
     lines is 0,points is 1, quads is 2.   
trailminspeed=<number>; 
     minimum unit speed required to have it.
trailwait=<number>; 
     time it takes to update the vertex array, usefull for lowering lag, high values = less lag, 1 is instant updates.

Log message:
*Added SyncedRead call-out GetUnitPiecePosDir(unitID, piece), this returns the global position and forward vector of the given piece (6 return values in total). The emphasis is on global, the previous call-outs only deliver relative values.
